Add Playlists section; clean up build artifacts from repo

- Wire Playlists star in index.html → Playlists/playlists.html
- Hub page: Aladin font, dynamic cards via build.py injection, no back-link
- 4 playlist pages: eclectica-experimenti, daydreamsoftime, soosfynwyn, theelfladymadeusdoit
- build.py: scans folder, extracts title+track count, regenerates hub cards in place
- Remove 21 tracked CSVs (moved with PlaylistPirate to ToolsnToys)
- Untrack Images/GEMINI.md, GEMINI-FIX.md, script-guide.md (agent artifacts)
- .gitignore: global rules for GEMINI*.md, HANDOVER.md, script-guide.md; Playlists build dirs
