feat: Major directory reorganization and cleanup

Reorganized project structure for better maintainability and reduced
disk usage by 95.9% (11 GB -> 451 MB).

Directory Reorganization (85% reduction in root files):
- Created docs/ with subdirectories (deployment, testing, database, etc.)
- Created infrastructure/vpn-configs/ for VPN scripts
- Moved 90+ files from root to organized locations
- Archived obsolete documentation (context system, offline mode, zombie debugging)
- Moved all test files to tests/ directory
- Root directory: 119 files -> 18 files

Disk Cleanup (10.55 GB recovered):
- Deleted Rust build artifacts: 9.6 GB (target/ directories)
- Deleted Python virtual environments: 161 MB (venv/ directories)
- Deleted Python cache: 50 KB (__pycache__/)

New Structure:
- docs/ - All documentation organized by category
- docs/archives/ - Obsolete but preserved documentation
- infrastructure/ - VPN configs and SSH setup
- tests/ - All test files consolidated
- logs/ - Ready for future logs

Benefits:
- Cleaner root directory (18 vs 119 files)
- Logical organization of documentation
- 95.9% disk space reduction
- Faster navigation and discovery
- Better portability (build artifacts excluded)

Build artifacts can be regenerated:
- Rust: cargo build --release (5-15 min per project)
- Python: pip install -r requirements.txt (2-3 min)
