```
tmux.Session.Rename(ctx: context.Context, name: string) -> (Session, error)
```

Rename changes the receiver session's name and returns a canonical freshly materialized [Session]. If the command succeeds but refresh fails, it returns the receiver with that error. A transport or context error can be delivery-ambiguous; no rollback is attempted. Invalid names are rejected before execution and match [ErrInvalidRequest].
