"""Regression test for the task-path endpoint-URL normalization fix.

Bug: the task executor passed ``task.endpoint_url`` verbatim to the model HTTP
call (unlike the chat path, which normalizes via ``build_chat_url``). A bare
OpenAI-compatible base such as ``http://host:11434/v1`` POSTed to a 404 and the
run silently reported "The model returned an empty response".

The fix routes every resolved task endpoint through ``_normalize_chat_endpoint``.
