* refactor: implement in-process worker architecture for hooks

Replaces spawn-based worker startup with in-process architecture:
- Hook processes now become the worker when port 37777 is free
- Eliminates Windows spawn issues (NO SPAWN rule)
- SessionStart chains: smart-install && stop && context

Key changes:
- worker-service.ts: hook case starts WorkerService in-process
- hook-command.ts: skipExit option prevents process.exit() when hosting worker
- hooks.json: single chained command replaces separate start/hook commands
- worker-utils.ts: ensureWorkerRunning() returns boolean, doesn't block
- handlers: graceful fallback when worker unavailable

All 761 tests pass. Manual verification confirms hook stays alive as worker.
