test(tools): add screenshot, budget and product checks; enforce file headers

- sim_screenshot.py finds the device drawing in the simulator window,
  crops the screen and compares it with approved golden images.
- check_budgets.py reads key=value DIAG/HARNESS lines (the simulator
  console escapes quotes, so JSON was dropped).
- ciq_test_report.py accepts SDK 9.2.0's real summary line
  `PASSED (passed=N, failed=N, errors=N)`; a captured log is a fixture.
- gen_products.py checks all manifest products are watches with
  API 5.0+ and at least 512 KB for apps.
- lint_project.py rule HDR001: every file carries the Author/Summary
  header (JSON keys, PNG text chunks; generated package-lock exempt).
- make_icon.py --all draws one icon per launcher size in use.
- Golden screenshots for fr255s, venusq2, fr70 and fr965.
- 44 tests, warnings as errors, ruff and mypy --strict clean.
