fix(cli): bound managed service shutdown

[thdxr]

Summary

• arm a native 10-second watchdog when a managed service begins shutdown
• force the daemon to exit if an Effect finalizer remains stuck
• clear the watchdog after successful shutdown so embedded callers are unaffected

Testing

• bun typecheck in packages/cli
• repository pre-push typecheck: 33 packages passed
• bun test test/service.test.ts -t "clean managed service shutdown removes its registration"
• bun test test/service.test.ts -t "deleting a managed service registration stops its owner"
