Add 5 animal lifecycle event handlers with TDD:
- HatchRecorded: Creates hatchling animals at brood/event location
- AnimalOutcome: Records death/harvest/sold with yields, status updates
- AnimalPromoted: Sets identified flag, nickname, optionally updates sex/repro_status
- AnimalMerged: Merges animal records, creates aliases, removes merged from live roster
- AnimalStatusCorrected: Admin-only status correction with required reason
All events include:
- Projection handlers in animal_registry.py and intervals.py
- Event-animal linking in event_animals.py
- Service methods with validation in animal.py
- 51 unit tests covering event creation, projections, and validation
- E2E test #7 (harvest with yields) per spec §21.7

Implement event deletion per spec §10 with role-based rules:
- Recorder can delete own events if no dependents exist
- Admin can cascade delete (tombstone target + all dependents)
- All deletions create immutable tombstone records
New modules:
- events/dependencies.py: find events depending on a target via shared animals
- events/delete.py: delete_event() with projection reversal
DependentEventsError exception added for 409 Conflict responses.
E2E test #6 implemented per spec §21.6.
