refactor: complete project restructure - clean and professional

🎯 New Structure:
- landing/ (root) - Only Makefile, .gitignore, .woodpecker.yml
- helm/ - Kubernetes deployment (with argocd inside chart)
- docker/ - Docker build configs
- peikarband/ - All source code (src, tests, assets, config, tools, docs)

✅ Changes:
- Moved Docker files: build/docker/ → docker/
- Moved Helm charts: deploy/helm/ → helm/
- Moved ArgoCD: deploy/argocd/ → helm/peikarband/argocd/
- Moved all source code to peikarband/
- Removed duplicate files (7 files)
- Removed old empty directories

🐳 Docker Fixes:
- Added npm retry configuration (fetch-retry-mintimeout, etc.)
- Added 3-attempt retry mechanism for reflex export
- Fixed ECONNREFUSED errors
- Updated paths for new structure

📦 Config Updates:
- Makefile: Updated all paths (docker/, helm/, peikarband/)
- .woodpecker.yml: Updated dockerfile and context paths
- .gitignore: Updated data/ path

🧪 Tests:
- ✓ Helm lint passes
- ✓ All paths validated
- ✓ Structure verified

📊 Result:
- Before: 20+ files in root, scattered structure
- After: 3 files + 3 directories, clean and organized
- Production-ready ✨
