test(tools): add test-log judge, docs and policy checks with tests

- ciq_test_report.py: decides pass/fail from Run No Evil output instead
  of monkeydo's unreliable exit code; writes JUnit XML.
- check_docs.py: offline check of relative links and GitHub anchors.
- lint_project.py: project rules (headers, no logging outside Diag,
  no secret-like literals, no network APIs or permissions).
- check_budgets.py with budgets.json: perf and memory gates.
- make_icon.py: reproducible launcher icon.
- 31 pytest tests, including Hypothesis fuzzing of the log parser and
  integration checks against the real docs and sources; ruff and mypy
  (strict) clean.

+"""Compare the app's debug diagnostics with the budgets in tools/budgets.json.
+
+Debug builds print lines like
+    DIAG {"event":"first_frame","startup_ms":123,"mem_used":4567,"mem_total":786432}
+(source/util/Diag.mc). app-diag.sh runs the app on each test device, saves the
+console output to build/diag/<device>.log, then calls this script.
+
+Usage:  check_budgets.py {perf,mem} LOG [LOG ...] [--budgets FILE] [--summary OUT.json]
+Exit:   0 within budget, 1 over budget, 2 missing or unreadable diagnostics.
