Switch PF2e data source from Pf2eTools to Foundry VTT PF2e

Replace the stagnant Pf2eTools bestiary with Foundry VTT PF2e system
data (github.com/foundryvtt/pf2e, v13-dev branch). This gives us 4,355
remaster-era creatures across 49 sources including Monster Core 1+2 and
all adventure paths.

Changes:
- Rewrite index generation script to walk Foundry pack directories
- Rewrite PF2e normalization adapter for Foundry JSON shape (system.*
  fields, items[] for attacks/abilities/spells)
- Add stripFoundryTags utility for Foundry HTML + enrichment syntax
- Implement multi-file source fetching (one request per creature file)
- Add spellcasting section to PF2e stat block (ranked spells + cantrips)
- Add saveConditional and hpDetails to PF2e domain type and stat block
- Add size and rarity to PF2e trait tags
- Filter redundant glossary abilities (healing when in hp.details,
  spell mechanic reminders, allSaves duplicates)
- Add PF2e stat block component tests (22 tests)
- Bump IndexedDB cache version to 5 for clean migration
