- Show a spinner with status table in `dstack attach` while the run is provisioning, matching the UX of `dstack apply`. - Handle `PortUsedError` gracefully in both `dstack attach` and `dstack apply` instead of showing a raw traceback. The error message suggests using `-p` to override the local port mapping. - Store the port number on `PortUsedError` for structured access. Co-authored-by: Cursor <cursoragent@cursor.com>
