Improvements:
- Uses curl -I to check which sources are reachable and fetch headers
- Queries GitHub API to get actual version tags
- Compares versions to determine best available release
- Prioritizes official releases (rfxn.com) when available
- Falls back to GitHub releases with version info
- Falls back to GitHub main branch as last resort
- Shows user which sources are reachable and which version will be downloaded
- More intelligent selection - now downloads newest version, not just first-available
- Longer timeout (15s) for slower networks
- Better error reporting with actual URLs for manual download
