기능 완성 우선 계획 반영: 혼합 복구 루프 E2E 추가 및 패리티 게이트 수치 동기화

- AgentLoopE2ETests에 mixed recovery 시나리오 추가: unknown-tool 오류 이후 file_write 경유, math_eval 대체 실행, 반복 한도 내 안전 종료를 검증

- 기존 권한/복구 검증과 충돌하지 않도록 이벤트 단정식을 경로 의존 최소화 형태로 정리

- 문서 동기화: AGENT_ROADMAP/NEXT_ROADMAP/CLAW_CODE_PARITY_PLAN의 최신 검증 수치를 ParityBenchmark 12/12, ReplayStability 12/12, 전체 372/372로 갱신

- 패리티 계획 문서에 혼합 복구 내구성 시나리오와 체크리스트 항목 수(9개) 반영

- 검증 실행: dotnet build(경고0/오류0), dotnet test --filter Suite=ParityBenchmark(12/12), dotnet test --filter Suite=ReplayStability(12/12), dotnet test(372/372), scripts/release-gate.ps1 통과
