On every tag push, build a %changelog entry from the git log since
the previous v* tag and prepend it to each spec. Stops the initial
entry from drifting further and catches bogus-date / stale-version
warnings automatically since the generated date always matches the
day the CI runs.
The generator drops "chore: bump version" commits (bot-authored,
noisy in user-facing changelogs) and merge commits. Author defaults
to the gitea-actions identity but can be overridden via
CHANGELOG_AUTHOR env var if a human release is desired.
Requires fetch-depth: 0 on checkout so git describe can see prior
tags and git log can reach them.
