fix(benchmark): evidence-gated scorer contract, false-positive discriminators, runner validity

- Confirm Validated hypotheses via canonical FIND-NNN.md matched in live-app
  terms (METHOD + endpoint route) alongside execution bundles
- require/require_any discriminators for shared-endpoint challenges;
  absence-type scoring for no-rate-limiting
- Runner: closeout timeout is a soft warning, not run invalidation
- ai_judge: whitelist legitimate closeout artifacts in schema-drift audit
- Align version surfaces to 3.1.0; move pyyaml to runtime deps

Calibration: known-good 20/20, known-bad 0/0. Latest run re-scored 4 -> 9.
