Some checks failed
dev release / build (push) Failing after 12s
Builds out the full v1 scope: a vendored+patched openscreen subset for low-latency Cast Streaming (Mirroring receiver 0F5096E8) alongside the existing Cast V2/HLS and new DLNA/AVTransport casting paths, breadcastd's Idle/Casting state machine with a private IPC socket, the breadcast GTK4 popup as a thin IPC client, and bread.cast.*/bread.command.cast.* breadd integration (device discovery, start/stop, mirroring lifecycle events). Also adds bakery/systemd/Forgejo CI packaging. Validated end-to-end against a real Chromecast/Google TV: negotiated Cast Streaming session, live pipeline playback, and daemon+GUI click-to-cast/ stop through the actual popup.
