[fix] load test direct dispatch mode bypasses scheduler hang - #9

Conversation
Rewrote run_inprocess() to submit requests directly to InferenceWorker.run_batch() via its ThreadPoolExecutor instead of going through the asyncio.PriorityQueue scheduler. The scheduler's run() loop timed out waiting on queue.get() because the event loop never yielded to let the scheduler enter its wait before requests began arriving — asyncio.sleep(0) was insufficient to fix the race. Direct dispatch eliminates the queue entirely: each concurrent request awaits worker.run_batch([payload]) which serialises through the worker's single-thread executor. 200 requests complete with 0 failures and real p50/p95/p99 latency percentiles are reported. https://claude.ai/code/session_01Vcjc9xwFH462bNmGdm9mjP
