* fix: wrap blocking readability call with asyncio.to_thread in web_fetch The readability extractor internally spawns a Node.js subprocess via readabilipy, which blocks the async event loop and causes a BlockingError when web_fetch is invoked inside LangGraph's async runtime. Wrap the synchronous extract_article call with asyncio.to_thread to offload it to a thread pool, unblocking the event loop. Note: community/infoquest/tools.py has the same latent issue and should be addressed in a follow-up PR. Closes #2152 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * test: verify web_fetch offloads extraction via asyncio.to_thread Add a regression test that monkeypatches asyncio.to_thread to confirm readability extraction is offloaded to a worker thread, preventing future refactors from reintroducing the blocking call. Addresses Copilot review feedback on #2157.
