Introduce a MassTransit saga state machine that correlates by TrackId and
tracks the two parallel processing slips (picture + audio):
- TrackProcessingStateMachine + EF-persisted TrackProcessingState
(pessimistic concurrency, EntityFrameworkRepository), migration added
- Starts on CreateTrackResourcesEvent; UpdateTrack{Picture,Audio}Activity now
publish TrackPictureProcessed / TrackAudioProcessed on success; when both
arrive the saga finalizes (Ready). Failure transitions to a Failed state
(cleanup wired in the next phase)
- Add LifeCycleStatus.Failed and the four outcome events
Verified: booted the Worker against RabbitMQ + migrated Postgres in Docker;
the saga endpoint 'track-processing-state' is configured and the bus starts
clean.
Build: 0 warnings, 0 errors.
