```
server.Server.isAlive() -> Promise<boolean>
```

Whether the tmux server is reachable.

A missing daemon, socket, or tmux executable answers false. Cancellation,
a command deadline, or an engine programming error still raises: none says
whether the server is alive.

## Example

```ts
if (await server.isAlive()) {
  await server.snapshot();
}
```
