tmux.Session.ResolveActivePane(ctx: context.Context) -> (Pane, error)
```

ResolveActivePane returns the active pane in this session's active window, read live. It lists that session's panes rather than taking a whole-server snapshot, because a pane row already carries which window is active. It returns [SnapshotLookupError] cardinality errors, which match [ErrNotFound] when nothing was found.
