Update README with current features and screenshots

- Cross-platform support (Windows/Linux) with Windows Updates and Winget
- Added dependency confirmation workflow and refresh token authentication
- New screenshots: History, Live Operations, Windows Agent Details
- Local CLI features with terminal output and cache system
- Updated known limitations - Proxmox integration is broken
- Organized docs to docs/ folder and updated .gitignore
- Probably introduced a dozen bugs with Windows agents - stay tuned

 ### Working Features
 - Server backend with REST API
-- Agent registration and check-in
-- Update discovery for APT packages and Docker images
-- Update approval workflow
-- Web dashboard with agent management
-- Local CLI tools (--scan, --status, --list-updates, --export)
-- Update installation system (alpha quality)
+- Cross-platform agent registration and check-in
+- Update discovery for APT, DNF, Docker images, Windows Updates, and Winget packages
+- Update approval workflow with dependency confirmation
+- Web dashboard with agent management and real-time status
+- Local CLI tools (--scan, --status, --list-updates, --export, --export=json/csv)
+- Update installation system with dry-run dependency checking
+- Beautiful terminal output with colors and severity indicators
+- Local cache system for offline viewing of scan results
+- Refresh token authentication for stable agent identity
+- Event-sourced database architecture for scalability
 
 ### Known Limitations
-- Update installation is minimally tested
-- DNF/RPM scanner incomplete
-- No rate limiting on API endpoints
-- No Windows agent support
+- No rate limiting on API endpoints (security improvement needed)
 - No real-time WebSocket updates
+- Proxmox integration is broken (needs complete rewrite)
+- Authentication system works but needs security hardening
