/**

* Atomically claim the oldest queued Web Designer task and print it as JSON.
|
|
* Prints an empty JSON object ({}) when the queue is empty. Used by the console
|
|
* runner's drain loop (agents/console/server.mjs) — the runner has no DB driver,
|
|
* so it shells out to this.
|
|
*
|
|
* php api/cli/tasks-next.php
|
|
*
|
|
* The claim is a single conditional UPDATE (status queued -> running) guarded by
|
|
* task_id, so two concurrent callers can never claim the same row.
