Fix: remove noisy debug print in OpenAI Responses model init

[segunakinfenwa-sketch]

Description

Summary

This PR removes an always-on print() statement from OpenAIResponsesModel.init that was polluting CLI output during normal runs.

Changes

• Replaced unconditional print() with logger.debug(...) so the message is only emitted when debug logging is enabled.

Why

• Prevents unwanted stdout noise for users running the CLI.
• Aligns with the project’s logging practices (debug output should be controlled via logging configuration/env).

Files changed

• src/cai/sdk/agents/models/openai_responses.py

Testing

• Ran the targeted test:
  • tests/tracing/test_responses_tracing.py
