 * tool's allowlist file) — the decision arrives once via the `onResolution`
 * callback and is otherwise one-shot. This store is that missing persistence:
 * a JSON file in the plugin state dir, so decisions survive gateway restarts,
 * redeploys, and plugin auto-updates.
 *
 * To make a tool prompt again, delete its entry from `tool-approvals.json`
 * (or the whole file) in the state dir.
 *
 * Load is synchronous (once, at plugin register()); writes are synchronous
 * atomic temp → rename, and only happen on an explicit user decision.
