-The sync task, visualizer drain thread, and artwork decode thread all use event flags for command signaling from the main loop and status reporting back. The artwork decode thread uses a simpler subset: `COMMAND_STOP` and `COMMAND_FLUSH`. The visualizer drain thread adds `COMMAND_CLEAR`, which discards buffered entries up to a 1-byte marker the network thread enqueues on `stream/start` and `stream/clear` (mirroring the sync task's clear-marker chunk) so frames received after the boundary survive; its `COMMAND_FLUSH` (drain to empty) is only used when the producer is already stopped (`stream/end`, cleanup).

 The filter is protected by `state_mutex_` so that `compute_client_time()` can be called from the sync task thread while `update()` runs from the main loop thread.

 The client listens on port 8928 by default. When mDNS is enabled it advertises `_sendspin._tcp` with the configured port so Sendspin servers on the local network discover and connect automatically; otherwise tell the server to connect with `ws://<this-host>:8928/sendspin`, replacing `8928` if you passed `-p`.
