Phase 2: full compendium across all categories + PF2e data

- Scraped PF2e reference from Archives of Nethys ES into public/data/pf2e/
  (spells, creatures, feats, equipment, weapons, armor, ancestries, heritages,
  backgrounds, archetypes, actions, conditions, deities) via scripts/fetch_pf2e.ts
- Registry-driven compendium: system toggle + per-category nav + generic filters
- 5e expanded: weapons, armor, feats, conditions added alongside spells/monsters/items
- PF2e data served as static assets (fetched, not bundled) for fast native parse
- Cross-links: add spell->spellbook / item->inventory to a campaign character;
  add monster/creature -> open encounter
- Condition tooltips in combat sourced from the conditions glossary
- Tests: registry filter unit tests, compendium e2e (browse + cross-link)
