Generates an rpm %changelog entry from git history and prepends it to the target spec file. Runs in release CI so every tag push gets a fresh dated entry covering the commits since the previous matching tag. Avoids stale dates, forgotten bumps, and bogus-weekday warnings. Inputs: spec path, version, optional release suffix, author, tag-pattern, exclude-patterns. The last two make the defaults (v* tags, filter bump-version chores and merges) tweakable for projects with different conventions. Migrated from inline logic in helexa/cortex so any project can adopt the same pattern with a single uses: reference. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

# Collects commits since the previous matching tag, drops filtered
