New clean API alongside old calendar_app: API endpoints: - /api/v1/schedule/calendars/ - Calendar CRUD - /api/v1/schedule/events/ - Event CRUD (with timezone) - /api/v1/schedule/rules/ - rrule RFC 5545 rules - /api/v1/schedule/occurrences/ - materialized recurrences - /api/v1/schedule/relations/ - meeting attendees Features: - Timezone support (pytz) - RFC 5545 rrule for recurring events - EventRelation for meeting participants - Clean, tested code (django-scheduler) - Parallel work with old /api/v1/calendar/ Old API untouched, works as before. Gradual migration approach (Strangler Fig Pattern).
