test(ci): de-flake tests, raise spec coverage, and tighten gates

- Fix a real bug in spec extractDescription: the requirement body excludes
  the header, so descriptions were always empty and every ADDED/MODIFIED
  requirement failed SHALL/MUST validation.
- Add spec tests (parse/validate/apply/DAG/config) lifting coverage from
  2.4% to 24.3%, plus a fuzz target and benchmarks.
- Make ContextDecay clock injectable; rewrite the timing-flaky decay tests
  deterministically.
- Un-skip TestParallelExecution, TestIntegration_FullSessionFlow, and the two
  config-apply tests; remove the blanket CI -skip.
- Golden test restores rootCmd globals; add make update-golden.
- Add testutil.Eventually/Never.
- CI: per-package coverage floors, FuzzParseDeltaSpec target, version fixture
  aligned to 0.0.1.
