Changelog Audit

Audit the pending files under changelog/, preview their combined Towncrier render, and optionally finalize or synchronize a release. CHANGELOG.md is the historical release record, not the source of pending entries.

Read changelog/README.md from the target ref before acting. Its fragment naming and content rules are authoritative.

Modes

• Main: audit and edit pending fragments. Never build a release section.
• Release branch: audit fragments, build the release section, then sort the generated section by user impact and update comparison links.
• Post-release sync: on main, bring back the exact release build commit so the tagged section's final wording and ordering win while only shipped fragments are removed.
