This branch supports vibration by achieving proper rumble reading from
games and uses regular eglantine/eden logic from ns1 to send them over.

Two threads closing the same fd both copied the descriptor and both called
Close(), so a host socket could be closed twice, and the second closesocket
could hit an unrelated socket that had reused the host fd. CloseImpl now
frees the slot under file_descriptors_mutex first and only that thread closes
the socket; the other gets EBADF.
OnProxyPacketReceived decompressed every room packet when any fd had a
socket, including native sockets and proxy sockets on other ports. Sockets
now report through AcceptsProxyPacket whether they want a packet, and only
those are collected, so an unwanted packet is not decompressed.
DecompressDataZSTD passed the frame's declared size straight to the vector
constructor, so a malformed or unsized frame from a room member threw on the
room thread. The new TryDecompressDataZSTD rejects invalid, unsized and
oversized frames, and bsd drops such packets with a warning.
DecompressDataZSTD now returns an empty vector for them instead of throwing.

Bananza's movie player acquires one decoded frame every time a released
output image's fence completes, and aborts (2111-3604) when the ring is
empty. Completing those fences at once after the end of a stream (the
Mario Kart World workaround) made it acquire from an empty ring the
moment its cutscene movies ended.
Released images now keep their normal pending fence after the end of a
stream. Stop (207) and Finalize (115) complete every fence handed out
so far, so a client that waits on its returned images after a movie is
still released when it stops the decoder.
EDEN_NX2_VDEC_EOS_RELEASE_NOW=1 restores the old immediate completion;
EDEN_NX2_VDEC_TRACE=1 logs every decoder call.
Tested on Bananza: the post-breakout cutscene movie ends and gameplay
continues (mining tunnel). Mario Kart World not retested.

- Complete pending fences immediately on release once the stream ends and no
frames remain to be processed, preventing infinite waits in movie teardown.
- Stop re-arming m_ready->room when an end-of-stream packet arrives or the final
frame is output, avoiding spurious wakeups and subsequent empty queue queries.
- Reset m_stream_ended when new input is submitted or on Flush/Stop.
Fixes an abort (2111-3604 / 0x1c286f) in Donkey Kong Bananza during the tutorial
transition scene when the video decoder stream ends.

A receive with MSG_DONTWAIT restored the blocking mode from the descriptor copy taken
before the call. When fcntl(SETFL, O_NONBLOCK) ran during the receive, the fd kept
reporting O_NONBLOCK while its socket blocked again. Receives now switch the mode only
for MSG_DONTWAIT and read the current flags under file_descriptors_mutex at both ends,
and SETFL changes the mode and the stored flags in the same critical section.
OnProxyPacketReceived decompressed each room packet once per matching socket while
holding file_descriptors_mutex, so every bsd call waited for it. It now copies the
distinct sockets under the lock, decompresses once without it and delivers the result.
Also reject fd == MAX_FD in IsFileDescriptorValid and PollImpl, which read past the
table, and guard the ProxySocket blocking and receive timeout setters with
packets_mutex, matching their reader.

bsd runs on three host threads, but its calls kept a raw reference into
the shared descriptor table while they used a socket. A close() on
another thread could then destroy the socket mid-call. Waking a blocked
room recv() on close made this happen every time. Every call now works
on a copy of the descriptor taken under the table lock, poll() keeps its
sockets alive while it waits, and close() resets the slot only if it
still holds the same socket.
accept() picked a free fd before blocking and only locked the write, so
another thread could publish a socket in the same slot. It now picks
and writes the fd in one critical section after Accept() returns. dup()
now re-checks the source fd under the lock.
A duplicated fd shares its socket, so the room packet loop queued each
packet once per fd. Deliver it once per socket.
NIFM: when the selected host adapter is missing, the room still works
and IsNetworkAvailable reports it, but GetCurrentNetworkProfile returned
an empty profile. Report a wired room profile in that case, and put the
room address on the first adapter in EnumerateNetworkInterfaces.

socket(AF_INET, SOCK_STREAM, 0) leaves the protocol unspecified, so the
TCP checks in ProxySocket::Recv and ReceivePacket missed such sockets.
recv() then waited for the timeout and returned EAGAIN instead of end of
stream, and partial reads dropped the rest of the packet. Keep the socket
type and use it for these checks. The protocol stays as it is, because it
is sent to other room members.
A MSG_PEEK reader leaves the packet queued, so notify every waiter when a
packet arrives instead of only one.

bsd:s, bsd:u and bsd:a share one file descriptor table, but each
service bound its own proxy packet callback, so every room packet was
queued three times on each socket. Bind the callback once.
The room thread walked the descriptor table without a lock while bsd
created and closed sockets, so it could reach a destroyed or not yet
created socket. Guard the table with a mutex, and publish a socket only
after it is created and initialized. Check airplane mode before an fd
is taken, so a refused socket no longer leaks its slot.
ProxySocket now initializes protocol, decompresses packets outside the
packet lock without copying the compressed data first, and keeps a read
offset for partial TCP reads instead of erasing from the front.
Add Network::GetRoomIPv4Address(), set only in the Joined and Moderator
states. NIFM uses it for network availability and for every reported
address, including EnumerateNetworkInterfaces and GetCurrentIpAddress,
so no call reports the room address while another rejects the network.

837133792d queues the GMMU maps on the GPU thread (GPU::RunInOrder) so the
service thread never waits for the texture cache. With the GPU split
(Low GPU accuracy) the GPU thread defers queued functions to its back, but
its front reads the command lists: it read the lists submitted after a map
through GPU addresses that weren't mapped yet. Pokopia stopped after its
first frame.
Add GPU::MapInOrder for the GMMU maps and the sparse tile remaps. It runs
in order like RunInOrder, and with the split it runs on the front after
draining the back, before the front reads further command lists. The
service thread still never takes the texture cache lock, and the back is
idle while the map changes the caches. Unmaps and the other queued work
still run on the back.

cce6d44af2 executes each command list entry from a copy of its words taken
at submit. Games submit command lists before writing them: the lists wait
behind a semaphore acquire, and the game writes their commands just before
it releases the acquire (Mario Kart World after present). The copies of
those lists were stale. Pokopia stopped after its first frame on macOS: its
GPU never reached the fence the game spun on (EDEN_NX2_PB_SNAPSHOT=0 made it
run again).
Count each channel's suspensions on an acquire and the resumes after them,
and record the count with each copy. A list copied while its channel was
suspended, or whose channel suspended since, reads guest memory instead.
Lists submitted and run without a wait in between keep the copy.
EDEN_NX2_PB_SNAPSHOT=0 still disables it altogether.

0f14696044 made PresentClientBuffer also wait for the current frame's
fence whenever the previous frame's wasn't reached. Mario Kart World's
GPU waits on semaphores its CPU releases only after the present returns,
so in that state the current fence can't be reached until the present
returns, and each such present stalled up to the 4 s deadline.
Wait for the current frame by default, but give up after a few ms once a
GPU channel was seen suspended on a semaphore acquire and wait for the
previous frame instead. EDEN_NX2_FRAMES_AHEAD=1 always waits for the
previous frame (with 0f14696044's current-frame wait when the GPU is
behind), =0 always for the current one. The scheduler gains a lock-free
flag so the present thread can see suspended channels.

4d6a13e3d9 and 3d6156434a added bounds checks to the nx2:gpu 216 sparse
map path, but the region checks still compute gpu_address + size, which
wraps for a guest-controlled size. 3d6156434a only guards size == 0 and
the memory offset on the map path, so an unmap (memory handle 0) with a
huge size matches a region through the wrapped sum and reaches
Nx2SparseTile, whose own check wraps the same way, and then
smmu.Unmap(device, size) with a giant page count.
Reject a request whose end wraps the address space before it is used,
for map and unmap alike, with a warning like the existing unknown-memory
check. Also compare by subtraction in the region lookups here and in
Nx2SparseTile and Nx2BackSparse, so none of them depends on the sum.

31b901b93b checked the TOC with unchecked arithmetic on counts and
offsets read from the file. The record-table size (u64 count times
record size) and u32 first_child + child_count can wrap, so the bounds
checks pass and later reads go out of bounds; the same holds for the
TOC range, name ranges, file extents and the meta range. A directory
that lists its own ancestor as a child also made BuildDirTree recurse
until the stack overflowed.
Bound the counts by the TOC size before multiplying, compare ranges by
subtraction, and widen the child range to u64. Walk the directory graph
once after parsing with an explicit stack and reject cycles and nesting
deeper than 128, so BuildDirTree can no longer recurse without bound.
The file is rejected with ErrorNUPBadFormat.

31b901b93b only cached a zstd member while it fit the 512 MiB cache.
Anything larger was never cached, so every Read() allocated the full
uncompressed size and decompressed the whole extent again, which makes a
multi-GB RomFS read in small chunks unusably slow. Members between 256
and 512 MiB evicted each other on alternate reads, and Insert copied the
vector so memory briefly doubled. Two threads decompressing the same
member also left a duplicate LRU entry and a wrong byte count.
The writer emits one zstd frame per member, so there are no frame
boundaries to seek by. Members larger than half the cache are now
streamed once into a temporary file under the cache directory and read
from there, using bounded memory. The file is removed when the
container is released. Smaller members stay in the LRU, which now moves
the vector in and ignores a duplicate insert.

The room host and room moderators are in the Moderator state, not
Joined, so the airplane mode override for joined rooms did not apply to
them and LAN Play still returned them to the menu. Accept both states.
Share the room address override between the NIFM profile and IP config
calls so they cannot drift apart.
recv() on a room TCP socket now waited for the receive timeout, because
Recv goes through RecvFrom. Room TCP sockets have no peer, so keep the
previous immediate end-of-stream result when nothing is queued.
Close() now drops queued packets and wakes a blocked recv, which then
fails with EBADF. The socket state that the room thread reads when it
queues a packet is now guarded by the packet mutex.

LAN Play through public lobby rooms failed in two ways.
With airplane mode on (the default), IRequest::GetResult rejected the
game's network request. Mario Kart World then opened the net-connect
applet and returned to the main menu instead of the LAN browser. A
joined room is the emulated network: its sockets only reach room
members. Count it as an available network for GetResult and
IsAnyInternetRequestAccepted.
With airplane mode off, players could open the browser but never saw
each other. Room fake IPs are spread over 192.168.0.0/16, and some room
servers give members different /24s. NIFM reported the host adapter's
/24 mask with the fake IP, so the games treated each other as off-subnet.
Report 255.255.0.0 in a room instead.

Routing recv() through RecvFrom made several old RecvFrom problems
reachable from the normal read path:
- A partial TCP read kept zero bytes in front of the unread data.
- A blocking read busy-waited with yield() and reported ETIMEDOUT.
- MSG_PEEK hit the flags == 0 assert.
- A UDP datagram larger than the buffer was dropped with EMSGSIZE.
Wait on a condition variable signalled when a packet arrives, and report
an expired wait as EAGAIN like an SO_RCVTIMEO timeout. Keep the existing
5s cap for sockets without a receive timeout. Allow MSG_PEEK. Truncate
oversized datagrams as BSD recv() does, and keep the unread tail of a
TCP packet for the next read.

When connected to an emulator room every guest socket is a ProxySocket.
Its Recv was a stub that always returned zero bytes, so games that read
UDP replies with recv() never received them. Mario Kart World LAN Play
reads its discovery replies this way, so guests never saw the host's
room in the LAN browser.
Delegate Recv to RecvFrom without an address, so queued room packets,
non-blocking, timeout, peek and truncation behaviour match recvfrom().

Donkey Kong Bananza names its resource size table without a version, so

PackOptions::metadata overrides the title name, icon and display version
found in the dump. A version override is written to the base and to the

version coming from the newest update that reports one, else the base.

Connect slept for a second while holding packet_mutex, so the host's
SyncNetwork reply could not be handled until Connect had already
returned success in StationOpened. Players could see each other's
group and enter it, but never actually met.
Wait on a condition variable instead, accept the reply only from the
selected host and session, and fail after five seconds. Check packet
sizes and senders, stop duplicate joins from taking another station,
and seed session IDs so separate networks don't share one.
The SDL frontend never called Network::Init, so its multiplayer
option could not join a room. Initialize and shut down networking
around the core.

--pack-nup (#271)
* file_sys: add a NUP packer for loose dumps
Packs a loose dump (exefs/romfs, base/, updates/<version>/ and
dlc/<titleid>/<n>/) into a NUP v1 container with the aligned record
layout. Every package is kept, files are deduplicated by SHA-256 and
compressed with zstd unless that does not shrink them, and files over
256 MiB are stored raw.
Output is byte-identical on every platform: compression is
single-threaded with every frame parameter set explicitly, and zstd is
always bundled so all builds use the same version.
A low-storage mode deletes each source file once its extent is synced
and journaled, and an interrupted run resumes from the journal.
Assisted-by: Claude Opus 5.5 (wrote the packer, its EdenPack-free dump detection, the aligned record layout and the deterministic zstd setup; ran the Raiders and Donkey Kong Bananza packs and boot checks)
* tests: cover the NUP packer
Round-trips a dump through NupContainer, checks standalone updates, a
bare exefs/romfs dump, low-storage resume and overwrite rejection, and
pins the hash of a packed dump so changes to the output are deliberate.
Assisted-by: Claude Opus 5.5 (wrote the tests, including the pinned output hash)
* qt: add Convert to NUP to the game list
Shown for loose dumps. Asks for confirmation with the estimated space,
offers low-storage mode, runs in the background with progress and
cancel, and resumes an interrupted low-storage conversion.
Assisted-by: Claude Opus 5.5 (wrote the Convert to NUP action and its progress and resume handling)
* cli: add --pack-nup <dump> [out.nup]
Assisted-by: Claude Opus 5.5 (wrote the --pack-nup option)

Fire Emblem: Fortune's Weave opens the keyboard with library version
0x160012 and a 0x530-byte config. Read with the Switch 1 layout, the
byte taken as use_utf8 belonged to initial_string_offset, so the name
entry returned UTF-16 and the game kept only its first letter. The
text prefix of the common part keeps its layout; the flags, lengths,
string offsets and dictionary fields move (checked against the game's
nn::swkbd::keyboardConfig2kbdConfig). Version 0x140010 is unchanged.

Command 106 was auto-stubbed, and Fire Emblem: Fortune's Weave treats
its empty reply as mode 0 and picks its 720p tier (rendering at 360p).
Report mode 4 (1440p) docked and 2 (1080p, the screen) handheld; the
game then renders at 720p and 540p and upscales to those.
EDEN_VI2_MAX_RESOLUTION_MODE overrides the mode.

The vi2 session is served by AM's thread on guest core 3, so the host
sleep in PaceToVblank held that core for most of every frame. Game
threads scheduled there only ran between presents: Fire Emblem:
Fortune's Weave's loader got one RomFS read per frame (33 ms apart
instead of about 4 ms), which doubled its load times.

Fire Emblem: Fortune's Weave's movie player queries (428) and maps (426)
each decoder output image, then blits it (RGBA, format 0xd5, block-linear
with 16-GOB blocks) into a texture of its own. The pool memory is process
memory (114) that no GPU mapping covered, so the blit read zeros and the
movies were black.
For decoder images, 426 now maps the image at its own address for the
GPU unless a mapping already covers it, and replies with the address,
the last byte's address and the image descriptor as our Eden tree does.
427 drops the mapping after the last unmap, as do 430 and 112. Images the
client reads on the GPU are written as block-linear RGBA, and the GPU
caches are invalidated after each frame. NV12 images and images read
with 961 keep the pitch-linear layout.

Present word 12 holds (swap interval << 16) | refresh rate. Presents were
always held to the next 60 Hz vblank, so Fire Emblem: Fortune's Weave,
which sends 0x2003c (interval 2) after its boot logos, ran at 60 fps and
double speed instead of 30.
Pace each present by its interval and rate (interval clamped to 1-4, rate
60 if outside 30-240 Hz) and log when the word changes.
EDEN_NX2_SWAP_INTERVAL=<n> forces the interval.
