aither-gemini 0.20.0

//! Example of using the native Code Execution tool with aither-gemini.
//!
//! To run this example:
//! 1. Set your `GEMINI_API_KEY` environment variable.
//! 2. Run `cargo run --example code_execution`
//!
//! This example demonstrates how to solve a computational problem by enabling
//! the native Code Execution tool, allowing Gemini to generate and run Python code.
