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.

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.
