Code Review / Critique Request: Unifying LLM providers & agent patterns behind shared core traits

The blog post is a request for critique on a Rust CLI project that brings LLM-powered agents into the terminal. The author, a university student, seeks feedback on implementation, code quality, and idiomatic Rust practices. The project focuses on decoupling agent execution patterns from specific LLM vendors, using a modular architecture to ensure separation between components. The post provides detailed architectural insights and asks for concrete improvement suggestions to enhance code maintainability and safety.
