Eric Traut 10aca93f18 Support graceful daemon shutdown on Windows (#42364) ...

## Why

Detached Windows processes cannot receive console signals, so app-server daemons
need another way to enter the existing graceful and forced shutdown flow.

## What changed

- Watch the path in `CODEX_DAEMON_SHUTDOWN_FILE` for a request addressed to the
  current process, and consume only a matching PID.
- Race daemon shutdown requests with Ctrl-C on Windows while leaving unmanaged
  launches on the existing console-signal path.
- Exercise the SIGTERM-equivalent graceful and forced WebSocket shutdown cases
  on Windows.

## Testing

Added unit coverage ensuring inherited control paths and malformed requests
cannot consume another process's shutdown request.
