// setupCommand assembles the `soundtouch-cli setup …` command group. Each
// subcommand wraps an existing pkg/service/setup helper — there is no new
// business logic in this file, only flag parsing and progress reporting.
//
// The group covers the manual provisioning loop documented in
// docs/analysis/SETUP-WEBSOCKET-EXPERIMENT.md and docs/guides/DEVICE-INITIAL-SETUP.md:
//
//	factory-reset → (manual: connect host to speaker's AP)
//	wifi-push     → (manual: switch host back to home Wi-Fi)
//	wait-online   → discover the speaker's new IP
//	urls          → point the speaker at AfterTouch
//	pair          → drive the WebSocket SETUP state machine
//
// The two "manual" lines are user-side Wi-Fi switches that cannot be
// automated portably (macOS, Linux, and Windows each use a different
// command). The wait-ap and wait-online subcommands poll for those
// switches so the user doesn't need to time them manually.
