## Summary

Deliver `@suaveplan/api-plugin-events` on the genesis branch from scratch at enterprise quality. Calendar/events plugin: event management (create/update/cancel), recurring event rules (RRule subset via `@suaveplan/datetime`), RSVP/attendance tracking, venue management, capacity limits, ticketing hooks, and an iCal feed export. Routes under `/events`. Per-table SurrealQL. Typed bus events: `calendar:event:created`, `calendar:event:cancelled`, `calendar:rsvp:confirmed`. Distinct from `@suaveplan/events` (the typed event bus package).
