/** Pure read of the in-memory pool index (Critical #2 fix).
 *
 *  CONTRACT: this function is a READ-ONLY computation. It MUST NOT
 *  write `index.json` (or any other file) as a side-effect. The
 *  "self-heal" property of rewriting index.json when it goes stale
 *  belongs to `rebuildIndexFromFs`, not here. List / search / recent /
 *  add-* verbs that need to mutate the on-disk cache should call
 *  `rebuildIndexFromFs` explicitly.
 *
 *  Edge case: if the pool root does not yet exist, this returns an
 *  empty index WITHOUT creating the directory. Callers that need a
 *  materialized root should use `rebuildIndexFromFs` or `mkdirSync`
 *  themselves.
