📁 Asset Organization Complete - Hierarchical Structure

✅ Organized assets into logical categories with subfolders:
- liki/ (kai, ana, gronk, npcs) - 342 PNG
- predmeti/ (orodja, semena, hrana, ostalo) - 226 PNG
- orozje/ (hladno, strelno) - 10 PNG
- rastline/ (posevki, drevesa) - 71 PNG
- efekti/ (voda, dim) - 22 PNG
- sovrazniki/ (zombiji, mutanti, bossi) - 68 PNG

✅ Removed incorrect DLC structure (198 empty folders)
✅ Created documentation for new structure
✅ Total: ~811 PNG files organized

From 61 top-level folders → 34 (optimized & clean)
