feat: RCDB-backed roller coaster filter with fuzzy name matching

- Add lib/park-meta.ts to manage data/park-meta.json (rcdb_id + coaster lists)
- Add lib/scrapers/rcdb.ts to scrape operating coaster names from RCDB park pages
- discover.ts now seeds park-meta.json with skeleton entries for all parks
- scrape.ts now refreshes RCDB coaster lists (30-day staleness) for parks with rcdb_id set
- fetchLiveRides() accepts a coasterNames Set; isCoaster uses normalize() on both sides
  to handle trademark symbols, 'THE ' prefixes, and punctuation differences between
  Queue-Times and RCDB names — applies correctly to both land rides and top-level rides
- Commit park-meta.json so it ships in the Docker image (fresh volumes get it automatically)
- Update .gitignore / .dockerignore to exclude only *.db files, not all of data/
- Dockerfile copies park-meta.json into image before VOLUME declaration
- README: document coaster filter setup and correct staleness window (72h not 7d)
