feat(repo): Add warning budget and maintainer audit

Freeze the accepted validation warning count at 135 so repo-state and release-state checks fail if the warning baseline grows silently while legacy warnings remain intentionally preserved.

Add a read-only maintainer audit command plus regression tests so maintainers can inspect repo health quickly without mutating files.
