Initial TopDeck: self-hosted ranked favorites

A single Go binary with SQLite that serves a public page of the owner's
ranked lists (movies, TV, albums, songs, video games, theater) and a
login-gated editor.

- Lists of 1–65,535 entries (100 recommended), several per category
- Search-to-add via TMDB, TheTVDB, IGDB, Deezer/MusicBrainz, Wikipedia;
  manual entry as a fallback
- Theater entries carry a production (Broadway, tour, …), venue and cast
- Artwork cached locally; URL override and uploads
- Drag, arrow and type-a-rank reordering; paginated for long lists
- 12 theme presets plus custom CSS
- First-run setup code or env-provided admin; bcrypt, rate-limited login,
  CSRF-guarded JSON API
- Dockerfile and docker-compose.yml
