test: add coaster name matching test suite

Extract matching logic into lib/coaster-match.ts (isCoasterMatch + normalizeForMatch)
so it can be imported by both the scraper and tests without duplication.

Add tests/coaster-matching.test.ts covering all known match/false-positive cases:
- Trademark symbols, leading THE, possessives, punctuation
- Subtitle variants in both directions (Apocalypse, New Revolution - Classic)
- Space-split brand words (BAT GIRL vs Batgirl)
- 4D subtitle extension (THE JOKER™ 4D Free Fly Coaster vs Joker)
- False positives: Joker y Harley Quinn, conjunction connectors

Run with: npm test
