/**
 * Render a compact "What's new" summary from a CHANGELOG.md body: one bullet
 * per feature/fix heading for each version in the range the user actually
 * moved through, `(fromVersion, toVersion]`. Headings are recognized in both
 * changelog formats — the current `- **Title.** prose…` single-line bullets
 * and the older standalone `**Heading**` lines. The verbose prose/sub-bullets
 * are intentionally dropped — the full notes live in the changelog.
 *
 * Returns colored lines ready to print, empty when nothing is in range.
