* feat(glance): show the favourite code in the glance (opt-in)cirakg9 days1-0/+2
| | | | | | | | | | | | | | | With "Show the favourite code in the glance" on, the glance shows the code of the first favourite TOTP or Steam entry without the PIN, with a countdown bar. The glance can't open the vault, so the About scan seals that entry under "g" (device key, aad OTPW-GL-1) after every change, and removes it when the option is off or no entry qualifies; the glance also reads the option itself. HKDF moves to its own module so the glance loads only the crypto it needs (37 % of its 64 KB). Manage entry gains "Mark as favourite (glance)" and "Remove favourite", queued for locked entries like the other changes. Lines are inset on round screens so the Instinct 3's curved glance corner doesn't cut them. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* feat(ui): add the list, OTP detail, PIN entry, menu, info screens and glancecirakg10 days1-0/+6
| | | | | | | | | | | | List with live codes and countdowns, adaptive rows and lazy headers; OTP detail with ring or bar, next code and HOTP next; PIN keypad or button selector with create, unlock, change, lockout display and pending promotion; native menu; glance with the entry count; self-test after the first frame; option properties with defaults. Codes are computed one per timer event, apart from drawing, for the watchdog. A UI-test build (uitest.jungle) starts with fake entries, PIN 123456 and a frozen clock.

* feat(crypto): add SHA-512, HMAC, PBKDF2, HKDF, AES-256 records and self-testcirakg11 days1-0/+36
- Sha512: FIPS 180-4 in Monkey C (no native SHA-512), rotations inlined with precomputed masks; constants derived from the primes, not typed. - Hmac: RFC 2104 over SHA-1/256/512 (native HMAC only supports SHA-256). - Kdf: resumable PBKDF2-HMAC-SHA256 job with calibration bounds (2,000-200,000 iterations) and HKDF-SHA256. - Aes: CBC with PKCS#7 over the native cipher; AES-256 chosen. - SealedBox: encrypt-then-MAC records (HKDF-split keys, length-prefixed aad, constant-time tag check before decryption). - SelfTest: known-answer tests for every primitive at start-up. - Bytes (wipe, constant-time equal), Clock (2038-safe widening, trusted clock), Jobs (bounded steps against the watchdog, timer runner).
