fix(cli): auto-detect org/repo in updates_xml_build from manifest and git remote

When --org/--repo are not provided and env vars are unset, the tool now
reads <org> and <name> from .mokogitea/manifest.xml, with a final
fallback to parsing the git remote URL. Fixes broken URLs with empty
org/repo segments in generated updates.xml.
