feat: enable api/llm model to converse in between each step

It would be beneficial to enhance the Codex CLI by allowing the LLM to engage in conversational interactions between execution steps. This feature would enable users to:​

• Review and discuss intermediate outputs before proceeding.
• Provide additional context or corrections during multi-step tasks.
• Iteratively refine actions based on real-time feedback.​

Implementing this capability would improve user control and adaptability, especially in complex workflows.​

Proposed Implementation:

• Introduce an optional conversational mode that pauses after each step, awaiting user input.
• Allow users to confirm, modify, or skip subsequent actions based on the assistant's suggestions.
• Maintain a history of interactions to provide context for ongoing tasks.​

This feature would align with the goal of creating a more interactive and user-friendly coding assistant within the terminal environment
