 * `index.json`: it materializes the pool root if needed, walks the
 * filesystem to build the in-memory index via `readPool`, and persists
 * the result. Callers that need the on-disk cache up-to-date should
 * call this function (or one of the add-* / rebuild-index CLI verbs
 * which call it internally).
