```
close(Server)
-spec close(t()) -> ok | {error, map()}.
```

Retire this endpoint's operations and one-shot clients, preserving the borrowed tmux server. Returns ok only after their cleanup completes; incomplete cleanup remains an explicit error. Closing an already closed retained handle is idempotent. The initiator controls endpoint lifetime. Separate control attachments are invalidated and asked to retire; use `tmux_control:close/1` before this call to verify those clients' cleanup too.

## Parameters

- `Server` (`t()`)
