## Summary
The `lint` and `integration_tests` CI jobs on `master` are currently failing. This PR fixes both:
1. **Lint (`nox -e lint`)** — 51 ruff violations in `scripts/validate_automation_tracking.py`:
- Sorted imports per isort convention
- Replaced deprecated `typing.List`/`Dict`/`Tuple`/`Optional` with builtin equivalents (`list`, `dict`, `tuple`)
- Removed unused `Optional` import and unused local variable `issues`
- Fixed trailing whitespace, blank-line whitespace, and 6 lines exceeding 88-char limit
- Replaced `dict.keys()` with `dict` in membership tests
- Added return type annotation to `main()`
2. **Integration tests (`nox -e integration_tests`)** — 1 failure in `robot/coverage_threshold.robot`:
- Removed `tdd_expected_fail`, `tdd_issue`, and `tdd_issue_4305` tags from the `Noxfile Contains Coverage Threshold Constant` test
- The bug this TDD tag tracked (issue #4305) is now fixed — `COVERAGE_THRESHOLD = 97` exists in `noxfile.py`
- The TDD expected-fail listener was inverting the passing result to a failure
### Local verification
- `nox -e lint` — All checks passed
- `nox -e integration_tests` — 1962 tests, 1962 passed, 0 failed, 0 skipped
### Files changed
| File | Change |
|------|--------|
| `scripts/validate_automation_tracking.py` | Fixed all 51 lint violations |
| `robot/coverage_threshold.robot` | Removed stale `tdd_expected_fail` tag |

Merged master into feature/q0-min-coverage. Resolved conflicts in:
- benchmarks/coverage_report_bench.py: combined AST and regex benchmarks
- docs/development/testing.md: merged both versions into comprehensive guide
- robot/coverage_threshold.robot: merged test cases from both branches
- implementation_plan.md: kept both Brent and Luis notes
Fixed coverage_threshold_config test that failed because it expected
a literal --fail-under=97 but our noxfile uses the COVERAGE_THRESHOLD
constant via f-string. Updated step to resolve the constant via AST.
