/**
 * Check pull request hygiene (changelog + commits)
 *
 * This script inspects the current git workspace to determine whether:
 * - The changelog (respecting CHANGELOG_FILE env override) has been modified
 * - A `[skip-changelog]` marker appears in commit messages
 * - Commits follow the conventional commit format
 *
 * Results are written to `$GITHUB_OUTPUT` when available so GitHub Actions steps
 * can consume them without relying on continue-on-error semantics.
