fix: ListDataSource cache and camera dependency resolution
Two critical fixes: 1. ListDataSource Cache Bug - Previously, ListDataSource.__init__ cached raw tuples directly - get_items() would return cached raw tuples without converting to SourceItem - This caused SourceItemsToBufferStage to receive tuples and stringify them - Results: ugly tuple representations in terminal/pygame instead of formatted text - Fix: Store raw items in _raw_items, let fetch() convert to SourceItem - Cache now contains proper SourceItem objects 2. Camera Dependency Resolution - CameraStage declared dependency on 'source.items' exactly - DataSourceStage provides 'source.headlines' (or 'source.poetry', etc.) - Capability matching didn't trigger prefix match for exact dependency - Fix: Change CameraStage dependency to 'source' for prefix matching 3. Added app.py Camera Stage Support - Pipeline now adds camera stage from preset.camera config - Supports vertical, horizontal, omni, floating, bounce modes - Tests now passing with proper data flow through all stages Tests: All 502 tests passing, 16 skipped
