One isolated tmux daemon and its descriptor-relative cleanup guard.

This value owns its foreground daemon and socket-directory lifecycle and
holds a no-start [`Server`] handle. The daemon uses a private explicit
socket and an owned empty config, creating no initial session. Escaped
[`Server`] clones share that handle's executor. [`TestServer::shutdown`]
closes the shared executor and reports graceful lifecycle and cleanup
failures; [`Drop`] performs synchronous forced best-effort daemon and file
cleanup whose failures cannot be observed.
