Harden MCP capability boundary fixtures
Harden MCP capability boundary fixtures - Add structured capability-boundary fixture data and deterministic drift variants - Map selected contract violations to registered capability/security labels - Strictly validate failure_label_on_violation as a registered string - Regenerate replay/admissibility artifacts and update tests Validated by GitHub Actions: npm run check, artifact drift validation, and related workflows.
