+ * prepare-release.mjs - Validate before version bumping
+ *
+ * Usage:
+ *   node scripts/prepare-release.mjs <version>
+ *   node scripts/prepare-release.mjs <version> --skip-validate
+ *
+ * What it does:
+ *   1. Ensures the git worktree is clean before starting
+ *   2. Runs `npm run validate` by default
+ *   3. Runs bump-version.mjs to update release files
+ *   4. Prints the remaining git steps (commit, tag, push)
