feat: add P3 hardening validation — 4 matrix + 2 extra cases (Phase 08)

Compact replay matrix on accepted P1/P2 live path: Matrix 1 (ChangedAddress): address change → cancel old plan → new assignment → new recovery → identity preserved → pins released Matrix 2 (StaleEpoch): epoch bump → invalidate → cancel plan → new epoch assignment → new session → pins released Matrix 3 (NeedsRebuild): unrecoverable gap → rebuild assignment → RebuildExecutor(IO=v2bridge) → InSync → pins released Matrix 4 (PostCheckpointBoundary): at committed=ZeroGap, in window= CatchUp via CatchUpExecutor(IO=v2bridge) → pins released Extra 1 (FailoverCycle): epoch 1 → failover → epoch 2 → recovery resumes → InSync. Logs: invalidation + cancellation + new session. Extra 2 (OverlappingRetention): plan1 acquires pins → cancel → plan2 acquires pins → cancel → ActiveHoldCount==0, MinWALRetentionFloor has no holds. Each test verifies all 5 evidence categories: entry truth, engine result, execution result, cleanup, observability Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
