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.
