feat(ai-judge): add advisory model catalog and strict corpus replay

- add versioned advisory model catalog shipped with the package and a fail-closed loader
- annotate the enforce session notice for untested, deprecated, and revoked models
- add --strict to corpus-replay with 0/1/2 exit codes and reject strict subset runs
- extract replay qualification into a pure module that recomputes matches and validates latencies
- remove the documented-but-unimplemented --thinking flag and stamp reports with a corpus version
- qualify gpt-5.6-sol as the first recommended entry and archive three real replay reports
- revise the corpus to 2026-08-21.2 changing unclear-forward expected defer to deny
