Both workflows looked for "**Hellion Chat <version>" as the changelog subblock header, but the yaml convention is "**v<version> — <subtitle>" (matches verify-changelog-sync.sh and the slim-rule grep). Plus the indent-strip was 2 spaces, but prettier writes the changelog block with 4-space indent. Both regressions silently failed every release-workflow run since the format change — likely why v1.4.3 was released manually. Sync header marker to "**v$version " and indent-strip to 4 spaces in both files.
