Code Review

This pull request updates the google-genai dependency to version 2.29.0 and introduces a comprehensive suite of new example scripts and tests demonstrating the interactions API across multiple capabilities, including bounding boxes, code execution, controlled generation, image generation, text generation, thinking, and tools. Feedback on the new code highlights a potential hang in headless environments due to the use of im.show() in the bounding box example, as well as several potential FileNotFoundError crashes across multiple image generation examples where output files are saved to a directory (output_folder) without first ensuring its creation.
