WIP: DM window tiers, expedition activity dedup, harvest gating

- Split advDMResponseWindow into a 12h low-priority tier for passive
  overnight-tolerant prompts (pet arrival/type/name); bump pet arrival
  chance 15% -> 30%.
- Skip zone_run activity lines for runs that belong to an active
  expedition — the expedition rollup is the source of truth.
- Loosen currentRoomCleared: Entry/Exploration/Trap allow harvest
  unconditionally (risk is the combat-interrupt roll); Elite/Boss stay
  gated on RoomsCleared.
