Split the dongle session into a fast probe (xone_open) and a background start (xone_start) that loads the firmware and initializes the radio on a worker thread, so the app UI never blocks. Add xone_state/xone_error for progress display, and select the firmware image per product ID when no path is given. The Swift app polls the state each second and shows idle/starting/ready/error plus the firmware build or error string. The session destructor joins the worker so quitting the app does not terminate on a joinable thread. Note in the CLI and transport that the recover/re-enumerate path should not be used yet: a crashed SIE drops off the bus, while the MCU watchdog recovers it after ~90s of quiet.
