 * warning and returns `undefined` — the caller keeps the inline result and
 * reports that the complete result could not be saved; search success never
 * turns into `isError` because spill storage is unavailable.
 *
 * @param ctx - the plugin context; `spillStore` is looked up opportunistically.
 * @param exec - the tool-execution context; supplies the owning session, tool name, and call id.
 * @param suggestedName - the backend-sanitized filename hint (e.g. `grep-results.txt`).
 * @param content - the complete formatted result to persist.
 * @returns the saved spill reference, or `undefined` when the result could not be saved.
