PlaybackEvent

Something that happened, delivered once.

Events are edge-triggered and lossless, so drive anything that advances the session from them: looping at the out point, auto-advance, analytics. Passive UI reads PlayerState instead.

Delivered with no replay, so subscribe before issuing commands.
