feat: Search results page, gapless removal, UI polish (v1.0.11)

- Add full search results page (/search?q=) with artist, album, song sections
- Fix search results column alignment (fixed-width Format column eliminates per-grid auto-sizing variance)
- Remove experimental gapless playback (caused song skipping and beginning cutoffs)
- Add known limitations to README and CHANGELOG (seeking, DnD reliability)
- Update GitHub Actions to Node.js 24 (checkout@v5, setup-node@v5)
- Add align-items: center to tracklist-header CSS
