Replace per-source services (LocationService, WeatherService,
TflService, FeedEngineService) with a single UserSessionManager
that owns all per-user state. Source creation is delegated to
thin FeedSourceProvider implementations per source type.

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

Manage per-user WeatherSource instances via FeedSourceProvider,
following the same pattern as LocationService. Wire into
FeedEngineService so weather data is included in the feed.

Manages per-user TflSource instances with individual line
configuration. Implements FeedSourceProvider so it can be
wired into FeedEngineService.
Adds TflSource.setLines() so line config can be mutated
in place, keeping engine references valid.
Also exports ITflApi from @aris/source-tfl for testability.

Migrates TFL package from old DataSource interface to new FeedSource
interface for use with FeedEngine.
Changes:
- Rename package from @aris/data-source-tfl to @aris/source-tfl
- Replace TflDataSource class with TflSource implementing FeedSource
- Add dependency on @aris/source-location for LocationKey
- Use normalized priority values (0-1) instead of arbitrary numbers
- Update tests for FeedSource interface
- Update README.md with new package name

Introduces FeedEngine that consumes FeedSource instances and manages
the dependency graph for context flow and item collection.
- Validates dependency graph (missing deps, circular references)
- Topologically sorts sources for execution order
- Runs fetchContext() in dependency order, accumulating context
- Runs fetchItems() on all sources with final context
- Supports reactive updates via onContextUpdate/onItemsUpdate
- Graceful error handling (continues after source failures)
Marks DataSource, ContextProvider, ContextBridge, Reconciler, and
FeedController as deprecated in favor of FeedSource + FeedEngine.

Implements FeedSource for WeatherKit API. Depends on location source,
provides weather context for downstream sources, and produces weather
feed items.

Implements FeedSource interface. Accepts external location pushes,
provides context to downstream sources, does not produce feed items.
Supports configurable history size.
