Remove priority field from FeedItem and engine-level sorting.
Add FeedItemSignals with urgency and timeRelevance fields.

Add listActions() and executeAction() to FeedSource for write
operations back to external services. Actions use arktype schemas
for input validation via StandardSchemaV1.
- ActionDefinition type with optional input schema
- FeedEngine routes actions with existence and ID validation
- Source IDs use reverse-domain format (aris.location, aris.tfl)
- LocationSource: update-location action with schema validation
- TflSource: set-lines-of-interest action with lineId validation
- No-op implementations for sources without actions

Sources that cannot provide context now return null
instead of omitting the method. The engine checks the
return value rather than method existence.

FeedEngine calls fetchContext then fetchItems with the same
context. Cache events by context.time reference to avoid
duplicate CalDAV round-trips.

A transient error on one calendar (e.g. shared calendar
with permission issues) no longer discards results from
all other calendars.

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
