HL RPG Mod

• Adds lightweight RPG progression on the server: players gain XP from killing mobs/players and from crafting items. XP rewards: 25 per kill, 10 per crafted output (multiplied by crafted quantity).
• Class is chosen automatically from the item in the player's hand: bows → Ranger, swords/axes/maces → Warrior, spellbooks/tomes/spell-tagged items → Mage. If no match, the last used class (or Warrior by default) is used.
• Leveling uses a simple curve (XP needed = 50 + 25 × current level). Excess XP rolls over, and multiple levels can be earned in one action.
• On level up, the world chat broadcasts Gained lvl: <player> <level> so everyone sees progress.
• Progress is tracked in-memory per player and per class; swapping weapons swaps the active class and keeps that class’s level/XPs. Data resets when the server restarts.
• No client assets required; everything runs server-side via the mod’s event hooks (kill feed and crafting events).
