feat(benchmark): valid detection benchmark spec + offline modules (groups 1-4)

Builds the benchmark from .kiro/specs/valid-detection-benchmark/brief.md:
sound labels from the fix (no SZZ), app-shaped verified positives,
ordinary negatives from the same repos, whole tool on unseen repos,
standard metrics.

Spec: requirements.md, design.md, tasks.md. Reuses the existing sourcing,
fix-site labelling, negative drawing, replay, and Wilson scoring; drops
the SZZ layer.

New offline modules under benchmarks/valid/:
- catalog.py  positives labelled at the fix site (never introducing/last_touch)
- verify.py   one LLM call per case (vulnerable? fix addresses it? reachable
              in-repo?) + human spot-check; this is the app-shaped filter.
              Honors the instrument rule: bytes read per function, reject on
              an empty read.
- assemble.py >=20x ordinary negatives + a frozen, deterministic manifest with
              the held-out guard
- metrics.py  precision (PPV), false alarms per 100 pushes, exploit-verified
              rate, and the plain headline, layered on score.py

36 new offline tests, 495 regression tests green. No network, no harvest,
no model calls in tests. Group 5 (the live pilot) is not started.
