feat(appd): include app_id in AppReady broadcast

ipc.rs: AppReady { session_id, app_id: String }.

runtime.rs: supervise() passes app_id (already in scope as parameter)
when building the AppReady broadcast message.

main.rs: supervisor integration test updated to use .. to ignore
app_id in the AppReady pattern match.
