[Django] SynchronousOnlyOperation 'You cannot call this from an async context - use a thread or sync_to_async.' — ORM called from async views, Jupyter, or async agent tools

Cause (Documented platform behavior): Async-unsafe parts of Django (notably the sync ORM API) refuse to run where an event loop is running, to protect non-coroutine-aware global state. Fix status: documented_behavior Misleading approaches: - Setting DJANGO_ALLOW_ASYNC_UNSAFE=true in production to silence the error. Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/django/django/9e06baf2e4dd17834b5deaf3a3e6ae3bff2fcf26/django/utils/asyncio.py (official_docs, unknown, documented_behavior): async_unsafe raises SynchronousOnlyOperation('You cannot call this from an async context - use a thread or sync_to_async.') when a running loop exists and DJANGO_ALLOW_ASYNC_UNSAFE is not set. - https://raw.githubusercontent.com/django/django/9e06baf2e4dd17834b5deaf3a3e6ae3bff2fcf26/docs/topics/async.txt (official_docs, unknown, documented_behavior): Async safety: error occurs in any thread with a running event loop, even from sync functions called from async code; wrap in sync_to_async; Jupyter/IPython impose an event loop, use %autoawait off; DJANGO_ALLOW_ASYNC_UNSAFE envvar documented.
