The chatgpt.com/backend-api/codex endpoint started sending SSE stream
events (response.output_text.delta, response.output_item.done, etc.)
with "output": null instead of "output": []. The OpenAI SDK's
parse_response() (lib/_parsing/_responses.py) iterates over
response.output without a None guard, raising:
TypeError: 'NoneType' object is not iterable
This caused all Codex Responses API calls to fail unconditionally.
Apply an idempotent monkey-patch at import time in the adapter module
that coerces response.output = None to [] before delegating to the
original parse_response().
