fn parse_versions_from_feed(xml: &str) -> Vec<Version>Expand description
Extract all semver-parseable versions from the <title> elements inside
<entry> blocks of an Atom feed.
The feed is generated by abbaye itself and has a predictable structure:
each entry’s title appears on its own line as <title>X.Y.Z</title>.
The feed-level <title>Abbaye Releases</title> will not parse as semver
and is silently ignored.
