- Move 12 markdown files from root to docs/ subdirectories - Organize documentation by category: • docs/troubleshooting/ (1 file) - Technical troubleshooting guides • docs/deployment/ (4 files) - Deployment and security documentation • docs/guides/ (3 files) - Feature-specific guides • docs/planning/ (4 files) - Planning and improvement proposals Root directory cleanup: - Reduced from 16 to 4 markdown files in root - Only essential project files remain: • CLAUDE.md (AI instructions) • README.md (Main project readme) • CLEANUP_PLAN.md (Current cleanup plan) • SRC_STRUCTURE_IMPROVEMENTS.md (Structure improvements) This improves: ✅ Documentation discoverability ✅ Logical organization by purpose ✅ Clean root directory ✅ Better maintainability
