## 📋 Review Summary

This Pull Request refactors and updates the Gemini CLI version by reorganizing its GitHub Actions workflows and defining new TOML configuration files for the gemini-invoke and gemini-review commands. The changes significantly improve the modularity and clarity of the Gemini CLI's integration with GitHub Actions.

🔍 General Feedback

• The new workflow structure using workflow_call for gemini-invoke.yml and gemini-review.yml is a good improvement for modularity and reusability.
• The security considerations regarding command substitution and untrusted input are clearly stated in the TOML prompt files, which is good for the agent's internal understanding.
• The use of actions/create-github-app-token@v2 for minting identity tokens is a secure way to handle permissions.
