Module lifecycle 

Cooperative cancel and FINALIZE ledger. One-shot lifecycle: INIT → EXECUTE → FINALIZE → EXIT.

Flow

1. Lifecycle::new creates cancel token and resource ledger
2. Commands may mark Chrome PID / profile in ResourceLedger
3. Lifecycle::finalize is idempotent and safe to call multiple times
4. Drop also calls finalize as a safety net

Safety

On Unix, finalize may send SIGTERM/SIGKILL to a recorded Chrome PID as last resort when primary Browser.close reap did not clear the ledger. Profile dirs and Chrome Singleton side-channels are wiped only when recorded in this ledger (never a host-wide chrome wipe).
