ArtistEngagementObserver: - creating: auto-fills organisation_id from parent Artist (RFC v0.2 D10 denormalisation), asserts artist.organisation_id == event.organisation_id; cross-tenant linkage throws CrossTenantEngagementException (extends DomainException, included in this commit). - saving: no-op marker reserved for Session 2 state-machine validation. - deleted: cascades soft-delete to Performance children, hard-deletes AdvanceSection children. AdvanceSubmission rows are immutable per RFC §5.4 and remain attached. PerformanceObserver: - saving: increments version by 1 on UPDATE only (D14 optimistic lock). MoveTimetablePerformanceRequest in Session 2 uses this for concurrent- edit detection. Both observers registered in AppServiceProvider::boot.
