Moves common asset operation methods (upsertAssets, removeAssets,
updateAssetOperation) from TimelineManager into PhotostreamManager
base class, making them available to all photostream implementations.
Updates all consuming components to use the more accurate 'upsertAssets'
naming instead of separate 'addAssets' and 'updateAssets' methods.
- Move asset operation methods to PhotostreamManager base class
- Replace addAssets/updateAssets calls with unified upsertAssets method
- Update type imports to use PhotostreamManager instead of TimelineManager
- Remove operations-support.svelte.ts (functionality moved to base class)
- Add abstract upsertAssetIntoSegment method for subclass customization
Create abstract PhotostreamManager and PhotostreamSegment base classes to enable reusable
timeline-like components. This refactoring extracts common viewport management, scroll
handling, and segment operations from TimelineManager and MonthGroup into reusable
abstractions.
Changes:
- Add PhotostreamManager.svelte.ts with viewport and scroll management
- Add PhotostreamSegment.svelte.ts with segment positioning and intersection logic
- Refactor TimelineManager to extend PhotostreamManager
- Refactor MonthGroup to extend PhotostreamSegment
- Add utility functions for segment identification and date formatting
- Update tests to reflect new inheritance structure
