How a pane relates to the process answering the request.

Three values rather than a boolean, because "not the caller's pane" and
"there is no caller" are different answers and an agent acts differently on
each.

## Members

- `Unknown` (constant): This process is not running inside tmux, so no pane is its own.
- `Own` (constant): Confirmed: the same tmux server, and the same pane.
- `Other` (constant): Some other pane, or a pane this crate cannot prove is the caller's.
