Phase 1: player character depth

- Inventory + currency + encumbrance vs carrying capacity
- Class resources with correct short/long/daily rest recovery (applyRest)
- Spellcasting: slots (+pact), known/prepared spells, derived DC + attack
- Defenses: 5e death saves/inspiration/exhaustion, pf2e dying/wounded/hero points
- Derived weapon attacks + passive perception via extended RulesSystem
- Dexie v2 migration backfills new fields; debounced save flushes on pagehide
- 9 new unit tests, new character-depth e2e; all green
