Added

• 16 new achievements (15 → 31 total), grouped into a new Category (Exploration/Combat/Survival/Farming/Loot) shown in /rpgmood achievements:
  • Exploration: Cartographer (discover every configured zone)
  • Combat: Untouchable (damage-free kill), Godslayer (kill all 4 major bosses), Overkill (level 30+ kill that drops a Legendary RPGLoot item)
  • Survival: Storm Chaser (survive a lightning strike), Death Tourist (die in 8 biomes)
  • Farming: Four Seasons, Noah's Ark, Beloved, Green Thumb
  • Loot: Legendary Hunter, Relic Bearer, Godslayer's Arsenal, Matching Set, Head to Toe, Dressed to Kill
• RPGLoot integration — six new Loot achievements read RPGLoot's item/player PersistentDataContainer tags directly (no Maven dependency either way, same soft-integration convention RPGLoot already uses to read rpgmood:level). New RPGLootIntegration and RPGLootAchievementListener.
• SeasonManager's season-change broadcast now actually unlocks seasons_first/four_seasons — it never did before (a gap from 1.2.0: the achievement was defined but never wired to the season-change event).

Fixed

• AchievementManager.ALL_ACHIEVEMENTS was a Set.of(...), so /rpgmood achievements rendered in unspecified (JVM-dependent) order. Switched to an ordered List.
