Phil Skentelbery b689e02e64 perf(feed): Batch load media and tags to fix N+1 query ...

Per v1.5.0 Phase 3: Fix N+1 query pattern in feed generation.

Implementation:
- Add get_media_for_notes() to starpunk/media.py for batch media loading
- Add get_tags_for_notes() to starpunk/tags.py for batch tag loading
- Update _get_cached_notes() in starpunk/routes/public.py to use batch loading
- Add comprehensive tests in tests/test_batch_loading.py

Performance improvement:
- Before: O(n) queries (1 query per note for media + 1 query per note for tags)
- After: O(1) queries (2 queries total: 1 for all media, 1 for all tags)
- Maintains same API behavior and output format

All tests passing: 920 passed in 360.79s
