 * Gate that sits between device selection and a REPL-class command's UI.
 * It opens a short probe session to check firmware compatibility:
 *
 *   - compatible (or undetermined — slow/silent device): render `children`
 *     and let the command connect normally.
 *   - incompatible: prompt to flash CLI-matched firmware (or flash straight
 *     away with `yes`), then exit with a "re-run" hint. We deliberately do
 *     not reconnect after flashing — the device resets and its USB-CDC port
 *     re-enumerates, so a clean re-run is more robust than resuming.
 *     Declining the prompt continues anyway: children render with
 *     compat 'best-effort' so their own connect warns instead of throwing.
 *
 * The probe session is always closed before rendering children or flashing
 * so the port is free for whoever runs next.
