final class LiveServer[F[_]]

object LiveServer
```

Observe a tmux server through a continuously updated [[signal]].

[[LiveServer.attach]] returns a `Resource` that closes the Java
[[io.github.libtmux.snapshot.ServerMirror ServerMirror]] when released. Read
[[failure]] to distinguish a quiet server from a stopped poller.

- `attach` (method): Listens through a control client attached to `anchor`, rebuilding on every announcement. The session is a required parameter: there is no arbitrary pick left to make, and a session that later disappears is `ServerMirror`'s own reconnect-or-`TargetGoneException` policy, surfaced through [[LiveServer#failure]] like any other cause.
- `failure` (method): `None` while still live; `Some(cause)` once the background poller has died. Never blocks.
- `signal` (property)
