Teknium aafe86d81a fix: prevent 'event loop already running' when async tools run in parallel (#2207) ...

When the model returns multiple tool calls, run_agent.py executes them
concurrently in a ThreadPoolExecutor. Each thread called _run_async()
which used a shared persistent event loop (_get_tool_loop()). If two
async tools (like web_extract) ran in parallel, the second thread would
hit 'This event loop is already running' on the shared loop.

Fix: detect worker threads (not main thread) and use asyncio.run() with
a per-thread fresh loop instead of the shared persistent one. The shared
loop is still used for the main thread (CLI sequential path) to keep
cached async clients (httpx/AsyncOpenAI) alive.
