The Telegram/Discord /model command's actual switch calls switch_model() directly on the asyncio event loop. switch_model() can fall through to a synchronous models.dev HTTP fetch (requests.get, 15s timeout) on a cold or expired cache, freezing the gateway for up to 15s and dropping the Telegram connection while a user switches models. The picker provider-list and fallback text-list sites were already offloaded (#41289), but the two _switch_model() calls — the picker callback and the direct /model <name> path — were not. Wrap both in asyncio.to_thread. Closes #20525.
