Marius CiepluchandClaude Opus 4.8 649bd42fc3 feat(gate): Phase 4 task 8 — lock the detection gate into CI ...

Make the >=90% recall / <10% FP detection gate a first-class, score-independent
CI step with non-regression guards.

- openultrasast.gate: canonical corpus map + DetectionMetrics/DetectionGateVerdict,
  evaluate_corpus/detection_gate (no score input — cannot be unblocked by score),
  merge_gate (ANDs the hard detection gate with the advisory-first score gate),
  within_tolerance, and a `python -m openultrasast.gate` entrypoint that exits
  non-zero on a breach. Wired as an explicit step in both the GitHub and Dagger
  pipelines.
- 8.1: pipeline tests prove a high/passing score cannot unblock a recall-breaching
  change; the gate fails below 90% recall or at/above 10% FP.
- 8.2: tests/golden/detection_baseline.json + a byte-identical baseline test for
  the default ruleset / empty ledger (44/47 = 93.62% recall, 0% FP).
- 8.3: within_tolerance band logic + a capability-gated HarnessX tolerance test.
- 8.4: zero-dependency guard — governance/scoring/benchmark planes never import
  HarnessX (sys.modules check + module-scope import scan).
- test_detection_benchmarks now sources the corpus/aggregation from the gate module.

128 passed, 3 skipped; ruff + mypy clean; detection gate PASS.
