Fix ArtifactPathInfo to reject non-standard paths

Add validation to ensure filenames follow Maven naming convention
(artifactId-version-...) and reject paths where the regex matches but
produces incorrect parsing results. This prevents mis-parsing of
non-standard paths like RPM artifacts that don't conform to Maven layout.
