fix: remove min query length requirement and improve search UI styling

- Remove 3-character minimum search query requirement
- Add dynamic padding to search results container
- Style search results with icons, grid layout, and hover states
- Fix missing semicolons in ChatInput event handlers
- Implement auto-scroll for selected search result
- Initialize vault cache after metadata resolution
- Update tests to reflect removed query length validation
