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.

Unifies DataSource and ContextProvider into a single interface that
forms a dependency graph. Sources declare dependencies on other sources
and can provide context, feed items, or both.
Deprecates DataSource, ContextProvider, and ContextBridge.

Implements @aris/data-source-weatherkit for fetching weather data from
Apple WeatherKit REST API.
- WeatherKitDataSource class implementing DataSource interface
- Feed items: current, hourly, daily, and alerts
- Priority adjustment based on weather conditions and alert severity
- Unit conversion (metric/imperial)
- Response validation with arktype
- Test fixtures from real API responses

TfL data source for tube, overground, and Elizabeth line alerts.
- Fetches line statuses and filters to minor/major delays and closures
- Sorts alerts by severity, then by proximity to user location
- Caches station data after first fetch
- Uses arktype for API response validation
- Supports API injection for testing
