Optimizes the `subscribeVideos` callback in `js/services/nostrService.js` to handle video updates incrementally, avoiding O(N*M) complexity during high-volume updates (e.g., initial load).
Changes:
- Modified `js/nostr/videoEventBuffer.js` to include deleted videos in the flushed batch, allowing consumers to handle deletions incrementally.
- Updated `js/services/nostrService.js` to process `updatedVideos` incrementally:
- Separates updates into active and deleted.
- Updates `this.videosMap` directly (removing deleted, adding/updating active).
- Filters and caches only the active updates (O(M)).
- Emits `videos:updated` with the full sorted list (derived from the updated map) to maintain API contract with consumers.
- Persists the full sorted list to localStorage.
This reduces the per-batch overhead significantly by avoiding O(N) filtering and map reconstruction for every batch of updates.

Separated the complex event buffering and flushing logic from `NostrClient.subscribeVideos` into a dedicated `VideoEventBuffer` utility class. This improves readability and maintainability of the `client.js` file.
- Created `js/nostr/videoEventBuffer.js`
- Updated `js/nostr/client.js` to use `VideoEventBuffer`
- Added unit tests in `tests/nostr/videoEventBuffer.test.mjs`
