Add UNO addbot, fix audit issues, add fishing to superstats, update README

UNO addbot:
- !uno addbot / !uno removebot for lobby bot management (WinBee, GwinBee)
- Bots ante from community pot, increasing the total pot
- Single human can start a game if bots fill remaining slots
- Per-bot display names throughout (replaces global unoBotName)

Audit fixes:
- Lobby display now always shows both humans and bots (was omitting bots on join)
- Slot check accounts for bots (was only counting humans)
- Color Roulette bot victim name fixed (was showing acting bot's name)
- Lobby display built under lock to prevent stale reads
- Bot name list separated from env var to prevent duplicates
- Extracted shared buildLobbyDisplay helper
- Inlined unnecessary nameOf closure in sudden death

Other:
- T5 masterwork drop rate reduced from 1.5% to 0.5%
- Added fishing stats to !superstatsexplusalpha
- Updated README with all new features

 #### Activities
 
-Three activity types across 5 tiers of locations (15 total). Higher tiers require higher character level and equipment.
+Four activity types across 5 tiers of locations. Higher tiers require higher character level and equipment.
 
 - **Dungeon** — combat XP, chance of death, best loot potential
 - **Mining** — mining XP, cave-in risk, ore and gem drops
+- **Fishing** — fishing XP, hazard risk, catch drops
 - **Foraging** — foraging XP, wildlife hazards, herb and reagent drops
 
 #### Mechanics
 
 - **Equipment** — 5 slots (weapon, armor, helmet, boots, tool) with tiered upgrades from the shop. Equipment degrades on bad outcomes and breaks at 0 condition.
+- **Masterwork gear** — rare skill-specific equipment drops from gathering activities (mining, fishing, foraging). 15 items across 5 tiers with decreasing drop rates (5% T1 down to 0.5% T5). Location-gated — drops only at matching tier. Auto-equips if better than current gear; otherwise goes to inventory for manual equipping via `!adventure equip`. Masterwork items provide a +5% skill bonus when the item's source skill matches the current activity. Character sheet marks masterwork items with a star.
 - **Treasures** — rare collectibles (up to 3) that provide passive bonuses (XP multipliers, death chance reduction, loot quality). Prompted to discard when at cap.
 - **Streaks** — consecutive days of activity grant escalating bonuses (XP, loot quality, death chance reduction). Resting or dying resets your streak.
 - **Grudge** — dying at a location marks it as your grudge. Returning there grants +10% success and +25% XP. Clears on success.
 - **Party bonus** — if two players independently visit the same location on the same day, both get +10% loot value.
-- **Death** — locked out until midnight UTC. You're automatically revived when the next day starts.
+- **Death** — locked out until midnight UTC. You're automatically revived when the next day starts. Death's Reprieve (surviving a lethal roll) sets all equipment to 1 condition instead of destroying it.
 - **Holidays** — on recognized holidays (~20/year across religious and cultural calendars), you get a second daily action. Hebrew and Islamic calendar support for floating holidays.
 - **TwinBee NPC** — takes a daily action (location tier capped by best player's combined level), distributes loot share to active players scaled quadratically by level, and occasionally gifts random buffs.
 - **Mid-day events** — random events can trigger between actions, delivering bonus loot, buffs, or narrative encounters.
 
 #### Arena (`!arena`)
 
-A multi-tier combat gauntlet independent of the daily adventure action. Fight through 5 tiers of 4 rounds each — 20 unique named monsters with escalating lethality. Earnings accumulate across rounds but are forfeited on death. After clearing a tier, choose to descend deeper (keep earnings at risk) or cash out. Death locks you out of both arena and adventure until midnight UTC.

Each fight produces a turn-based combat log (Dragon Quest style) with fabricated HP pools and action narration — the outcome is determined by the roll, the log is assembled backward from the result. Arena losses award +60 participation XP.
