fn collect_released_identifiers(
releases_dir: &Path,
) -> Result<ReleasedIdentifiers>Expand description
Scan every existing release CUE file for the sha: and pr_number:
fields inside its commits: array and return the union as two sets.
We extract via simple regexes rather than running cue export. The shape
of these files is well-defined (auto-generated and cue fmt-normalised
against urls.cue) so this is the cheapest correct option, and avoids a
runtime dependency on the cue binary just for de-duplication.
