Add masterwork rework, arena combat log, Death's Reprieve fix, and wordle improvements

Adventure — Masterwork Rework:
- Expand from 3 generic items to 15 tiered masterwork items across
  mining (weapon), fishing (armor), and foraging (boots) with per-tier
  drop rates (5%/4%/3%/2%/1.5%) and location gating
- Skill-specific cross-skill bonuses replace flat masterwork check
- Auto-equip if better, silent discard for duplicates, inventory for rest
- Add !adventure equip command for manual masterwork equipping
- Tiered room announcements: T1-2 DM only, T3 quiet, T4-5 full
- First-drop detection with special message
- Character sheet shows ⭐/⚔️ markers for masterwork/arena gear
- Sell protection for special gear in shop

Adventure — Arena Combat Log:
- Turn-based Dragon Quest style narrative for arena fights
- Outcome-first design: roll determines win/loss, log assembled backward
- No-repeat flavor text via actionPicker with per-pool tracking
- 60 participation XP on arena loss

Adventure — Death's Reprieve Fix:
- All equipment set to 1 condition instead of death-level degradation

Wordle:
- Refactored word sourcing and expanded fallback word list
- Simplified Wordnik integration
