patch

Engine: self-heal git worktree add failures classified as "missing but already registered worktree" by pruning the stale registration and retrying once. Recovery is observable via new run-audit events worktree:stale-registration-detected, worktree:stale-registration-recovered, worktree:stale-registration-recovery-failed.
