Replace JSON API-based update checking with Joomla-style updates.xml
that supports multiple update streams (stable, dev, security).
Changes:
- Add updates.xml at repo root with stable/dev/security channels
following the same XML structure as MokoOnyx and other Joomla repos
- Rewrite updatechecker module to parse XML with channel filtering
- Add CHANNEL setting to [update_checker] config (default: stable)
- Show channel name and docker pull command in admin dashboard banner
Config example:
[update_checker]
ENABLED = true
CHANNEL = stable
