libtmux_mcp.tools.session_tools.get_session_info(session_id: str | None = None, session_name: str | None = None, socket_name: str | None = None) -> SessionInfo
```

Return metadata for a single tmux session (ID, name, window count, activity).

Use this instead of list_sessions + filter when you only need one
session's info. Resolves by session_id first; falls back to
session_name.

## Parameters

- `session_id` (str | None): Session ID (e.g. '$0').
- `session_name` (str | None): Session name.
- `socket_name` (str | None): tmux socket name.

## Returns

SessionInfo
    Serialized session metadata.
