Phase 5: active items — room-clear charged, dedicated pedestals, Space to use

- ACTIVES table with 10 actives (Bone Nova, Offal Bomb, Blood Transfusion,
  Cleaver Storm, Butcher's Bell, Marrow Draught, Slaughter Time, Panic Room,
  Skinner's Coin, Gut Reroll); charges accrue +1/combat room, +2/boss
- Dedicated 'active' pickup with weapon-style swap-drop; 30% boss / 15% item-room
  bonus pedestal spawns; flat +2 powerScore while held
- HUD active slot with charge pips + READY state; ACTIVES help page (12 pages);
  teal medallion frame variant in draw_sprites.py; 10 generated icons
- Procedural Sfx.active()/activeEmpty() (real clips deferred to audio batch)
- Fix: toast panel width now fits the wider of title/subtitle and clamps to screen
- Bump asset cache to v=40
