● Let me read the current state of the test file to understand the compilation
  error and fix it.

● Read 1 file (ctrl+o to expand)

● Let me check the common test module to understand the run_until_complete
  implementation and the Send trait issue.

● Read 1 file (ctrl+o to expand)

● Now I understand the issue. The run_until_complete function uses non-Send
  types internally (like PgListener), so it can't be spawned with tokio::spawn.
  The correct approach for stress testing is to push all jobs to the queue
  first, then let a single worker process them concurrently. This is actually
  more realistic since it tests the actual concurrent V8 execution.

  Let me fix the stress tests:
