Code Review

This pull request updates model references across various quickstarts, examples, and documentation files to use the newer gemini-3.6-flash and gemini-3.5-flash-lite models. The review identified critical issues including a Python SyntaxError in the guardrails example and a TypeError in the Haystack retrieval example due to malformed model assignments. Additionally, several display names and descriptions in the managed agents quickstart need to be updated to match the newly referenced model versions.
