  - POST /modding/api/modpack/create (bundle mods)
  - GET /modding/api/modpacks (browse packs)
  - DELETE /modding/api/content/{id} (moderation)

Database:
- Added ModPack entity for mod bundles
- Extended Car with IsCustom, CustomAuthor, CustomVersion
- Extended GameAsset with IsCustomContent, CustomAuthor
- Supports versioning, ratings, download tracking

Configuration:
- CustomAssetsPath & ModsPath settings
- EnableModding flag
- Upload size limits (100MB cars, 200MB tracks)

Documentation:
- MODDING_GUIDE.md: Complete modding system guide
  - API endpoints & examples
  - Content creation workflow
  - Tools & resources
  - Community guidelines
  - Example scripts

Features:
 Upload custom cars (models, textures, audio)
