Add Tokyo livehouse event aggregator service

Full-stack React Router v7 app that scrapes event listings from major
Tokyo live venues (Liquid Room, WWW/WWW X, Shibuya O-EAST, Shinjuku LOFT,
Club Quattro) and stores them in SQLite for browsing and search.

- Modular scraper architecture: add a new venue by dropping a file in
  app/scrapers/ and registering it in index.ts
- Routes: /events (filter by keyword/venue/date), /events/:id, /venues,
  GET /api/scrape
- EventCard shows artist, date/time, venue, ticket URL, and fee
- Post-scrape per-venue Markdown files generated to events/ (dev reference)
- /add-livehouse Claude Code skill defined in .claude/commands/
