fix: remove lesser stream copies, each stream updates independently

Joomla picks the HIGHEST version via version_compare() across ALL
entries. Lesser stream copies (02.17.00-dev) at the same base version
as stable (02.17.00) would never be selected because dev < stable.

Each stream now updates only when its own release happens:
- stable: on merge to main
- dev: on auto-bump after dev recreated from main
- rc: on promote-rc

The dev stream naturally gets 02.17.01-dev (higher than 02.17.00)
because auto-bump runs on the recreated dev branch.

Also sorts updates.xml entries dev→stable (dev first).
