v1.0.4 - Quick Access reorder, performance improvements, search fixes

- Quick Access drag-to-reorder: drag notes to rearrange, order persists
- Quick Access preserves order when moving notes between notebooks
- In-note search: debounced input, proper scroll-to-match
- Panel resize: RAF-batched updates, editor containment during resize
- Thinner resize handles (3px)
- Note list: removed transition, added CSS containment for 1200+ notes
- Escape closes Settings and Info panels
- Fix Quick Access cache invalidation on remove
