* Remove explicit openai dependency from requirements.txt
openai is no longer directly imported; it comes in as a transitive
dependency of litellm. Pinning it explicitly risks version conflicts.

* Restore openai==1.101.0 pin in requirements.txt
litellm==1.82.0 and openai-agents have conflicting openai version
requirements, but openai==1.101.0 works at runtime for both.
The pin is necessary to prevent litellm from pulling in openai>=2.x
which would break openai-agents.

* Remove explicit openai dependency from requirements.txt
openai is not directly used; it comes in as a transitive dependency
of litellm. No openai-agents in this branch so no pin needed.
