Add a 'sendspin source' command that runs a source client: capture audio from a local input (line-in/microphone) or a sine test tone, encode it (PCM, FLAC, or Opus via PyAV), and stream it to a server, which mixes and distributes it to players. The server controls when the source streams. - source_utils: PyAV SourceEncoder (exposes raw codec header) + RMS level - source_stream: SourceStreamer capture loop (sounddevice / sine), server start/stop handling, optional line-sense signal reporting - cli: 'source' subcommand and 'audio-devices inputs' listing - audio_devices: input-device enumeration - settings: SourceSettings persistence (settings-source.json) - README: source mode documentation

Adds a
sendspin sourcecommand: run as a Sendspin source client that captures audio from a local input (line-in/microphone) or a synthetic sine test tone, encodes it (PCM, FLAC, or Opus via PyAV), and streams it to a server, which mixes and distributes it to players.Implements the client side of the
source@v1role (Sendspin/spec#105).Depends on Sendspin/aiosendspin#286 (the
source@v1protocol + client SDK). Theaiosendspinversion pin here must be bumped to the release that includes it before this can merge — hence draft.Supersedes #123, which targeted the earlier
input_stream/*proposal.What's added

The server is the sole initiator of streaming (a source stays idle until told to start). A device may run both
sourceandplayer; it never plays its captured input locally.Testing
ruff+mypyclean;pytest: 155 passed (13 new, incl. a cross-repo round-trip: encode with the CLI encoder then decode with the aiosendspin server decoder, for PCM/FLAC/Opus).
