feat: add Apple Calendar source package

Add @aris/source-apple-calendar for fetching iCloud
calendar events via CalDAV using tsdav and ical.js.

- CalendarSource implements FeedSource with fetchItems
  and fetchContext for downstream context
- CalendarCredentialProvider interface for token injection
- CalendarDAVClient interface for testability
- iCal parser extracts full event data including
  attendees, alarms, organizer, and recurrence
- Priority based on event proximity to current time
