Code-review findings on 085f7b99c: a bare date like 2026-07-22 qualified
as a distinctive slug, so unrelated failure reports quoting the same date
silently converged (and the date outranked a real file-path anchor in the
sorted-first pick); reject slugs whose segments are all hex/numeric.
Also render non-http(s) sourceMetadata.issueUrl values as plain text to
block javascript:-scheme links from API-supplied metadata.
