```
tmux.Pane.SetTitle(ctx: context.Context, title: string) -> (Pane, error)
```

SetTitle sets the title of the receiver's exact linked pane. tmux expands format expressions in title; the value is not a shell command. SetTitle then refreshes by PaneID, so the returned canonical [Pane] may carry a different linked-session or winlink context. If the mutation is accepted but refresh fails, SetTitle returns the original receiver with that error.

Completed stderr produces a redacted [CommandError]; nonzero exits without
stderr are followed by refresh. Transport errors return zero and are
delivery-ambiguous.
