Phase 7: structured ruleset data (Open5e 5e + Foundry PF2e classes)

- Scrapers scripts/fetch_open5e.ts (classes/races/backgrounds/feats, CC-BY/OGL) and
  fetch_foundry_pf2e.ts (25 PF2e classes, OGL/ORC) → normalized JSON in src/data/srd
  + public/data/pf2e/classes.json.
- src/lib/ruleset/normalize.ts: pure, tested normalizers → unified RulesetClass
  (hit die, key abilities, saves/ranks, perception, skills, caster, subclasses, profs).
- compendium loaders (loadClasses/loadRaces5e/loadBackgrounds5e) + a "Classes" tab for
  both systems (ClassDetail) with full stats; Bestiary stays the default category.
- Data-source attribution in Settings. Feeds the Phase 5 builder.
