Codex only authenticates a custom model provider from env_key,
http_headers, env_http_headers or a token command — auth.json is
read solely by the built-in openai provider. Writing OPENAI_API_KEY
there left every request unauthenticated (401 Missing API key) while
clobbering an existing ChatGPT login.
Put the key in [model_providers.9router.http_headers] instead, and
drop the auth.json write. Also move the subagent model to the
agents.default_subagent_model scalar: agents.<role> now declares a
custom role and requires a description, so the old [agents.subagent]
table was discarded with a startup warning. DELETE still clears
auth.json to repair machines configured by the previous version.
