v0.1.3 - better error messages

Improves error messages when litellm auth fails (e.g. due to missing env key).

Use LiteLLM

• Switched from Google's Gemini SDK to LiteLLM.
• Gemini remains the default model, but you can now select other models through the .toml configuration settings.
• @sicksubroutine moved us from setuptools to hatchling and fixed a lot of issues around the tests

Handle large websites

Fixed an issue where the input got truncated and the llm hallucinated the rest.
