- Remove all file revert/delete logic from check_plan_approval_gate: no more git checkout or fs::remove_file calls. The gate only warns. - Remove reverted_files field from ApprovalGateResult::Blocked. - Add get_dirty_files() helper to snapshot dirty files as a HashSet. - Capture baseline dirty files when plan mode starts (set_plan_mode). Pre-existing dirty files are excluded from gate checks so they never trigger blocking. - Add 5 new unit tests covering non-destructive behavior, baseline exclusion, and mixed baseline/new file scenarios. - Update integration test to match new non-destructive semantics.
