feat: enhance Windows scripts to match Mac feature parity

Windows-Start.bat:
- Fix duplicate browser tab opening (was opening 3 tabs)
- Read gateway token from config instead of hardcoding
- Add config sync from legacy location
- Use delayed browser open for gateway startup time

Windows-Menu.bat:
- Fix Node version display bug (double %% issue)
- System info: add Windows version, architecture, memory, disk size
- Check updates: auto-fetch latest version from npmmirror, one-click upgrade
- Disk cleanup: show directory sizes, clean old backups/logs/npm cache
- Log management: add export to desktop, clean logs older than 7 days
- Restore backup: numbered list selection instead of typing folder name
- Kill processes: add confirmation prompt before killing
- Chat platforms: individual setup guidance per platform

Windows-Install.bat:
- Add Node.js online download fallback (was exit-only when missing)
- Add system Node.js version check (require v20+)
- Generated start.bat now has port detection loop
- Show install size on completion

Windows-Diagnose.bat:
- Add system info logging (Windows version, architecture)
- Add config file and model configuration check
- Expand port scan to full 18789-18799 range
- Show OpenClaw version in test output
