- Add level-up dialog (ApplicationV2) showing features gained per level
- Class features with `changes` arrays auto-create Active Effects
- Valor I/II/III on Fighter reduces crit threshold cumulatively (-1/-2/-3)
- Perk selection UI in dialog (awaits perk compendium content)
- Fix duplicate item creation bug (was double drop handling)
- Configure proper dragDrop in ActorSheetV2 DEFAULT_OPTIONS
- Add ancestries and classes compendium packs with LevelDB format
- Docker compose PUID/PGID for proper file permissions
Key patterns established:
- Class progression stored in item.system.progression[]
- Features with changes[] become ActiveEffects on level-up
- applyClassFeatures() is idempotent (checks existing effects)
- updateClassFeatures() handles level changes incrementally
