 Planned work, roughly in order:
 
-1. Add MSP parsing as a second adapter to the shared media request and playback layer.
-2. Add aliases, triggers, timers, optional transcripts, and configurable command shortcuts.
-3. Add multiple simultaneous sessions with independent output, media, and speech queues.
-4. Add localization catalogs and package/signing automation for releases.
