feat: Add Loot Manager plugin skeleton (Phase 4)

Created skeleton implementation for first paid module ($9.99).

Plugin Features:
- Loot profile system with container multipliers and custom loot tables
- OnLootSpawn/OnEntitySpawned hooks for container loot modification
- Six container types: normal, elite, mine, barrel, food, military
- Chat command: /loot.profile [name] for admin profile switching
- Per-item config: shortname, min/max amount, spawn chance, skin ID

Status:
- Hooks functional, profile switching works via chat command
- Dashboard UI integration pending future iteration
- Auto-deploy system pending future iteration
- Migration 009 already includes module seed data
