Subject: [PATCH] test(W7c): skill-validation matches three capital-letter pins
 on meaning

W7c (t08 F2, F4, F5). One test file; only these three pins change.

Removed assertion groups: none. Loosened, invariant kept as a free
case-insensitive meaning check:
- `MUTUALLY EXCLUSIVE` (codex skeleton) -> one codex mode per invocation:
  `/mutually exclusive/i` (t08 F4).
- `skip the Codex passes ONLY` (review adversarial) -> `codex_reviews=disabled`
  skips only the Codex passes, Claude adversarial still runs:
  `/disabled[^\n]*skip the Codex passes only/i` (t08 F5).
- `If any in-branch failures remain unfixed, **STOP**. Do not proceed` (ship
  tests section) -> unfixed in-branch failures block advancement:
  `/in-branch failures remain unfixed ... stop ... do not proceed/i` (t08 F2).
  Also covered by gate E2E ship-triage (gate).

Cosmetic pins dropped: capitals and bold only.

Mutation log: .context/mutation-skill-validation.md (6 mutations, 0
unexpected: 3 rule deletions red; 3 lower-case rewordings green).
