- Add new transmission ansible role using homebrew + brew services
- Configure transmission to download to ~/transmission with localhost-only RPC
- Modify kiwix role to use transmission for downloading ZIM archives via BitTorrent
- Add role dependency so running --tags kiwix auto-runs transmission
- Keep fallback to direct HTTP download when kiwix_use_transmission: false
- Symlink completed downloads from transmission dir to kiwix-tools dir
This reduces load on kiwix.org servers and allows downloads to continue
in the background without blocking ansible runs.
