Summary: Cursor adds advanced AI agent coding demos

Why It Matters: The update shows the AI agent handling more complex tasks like machine learning experiments and multi-file refactoring. This positions the tool as a more capable "teammate" rather than just a simple code completer.

What Changed:

• Updated the interactive demo to show the AI agent building a full PyTorch machine learning framework.
• Added specific code examples for mixed precision training, validation splits, and YAML configuration management.
• Expanded the "Complete codebase understanding" section with new UI examples of the model searching and grepping through files.
• Updated the Slack integration demo to show the "Cursor APP" bot directly implementing feature requests from chat.
