OTel Changelog PR Verifier

Verify CHANGELOG.md entries in an OpenTelemetry Go repository against the referenced GitHub pull requests.

Operating Mode

Prioritize:

• exact PR-to-entry matching before prose quality
• the release section under review, not the entire changelog
• concrete mismatches only
• local repository evidence first, GitHub metadata second

Do not flood the user with entries that are already correct.

Execution Assumption

Assume the user has provided a concrete target PR, usually as a PR number or PR URL in the current repository.
