Summary: Cursor updates homepage with advanced AI agent demos

Why It Matters: The update shows the product moving from simple code completion to complex, multi-step "agentic" workflows. This signals a shift toward AI that can plan and execute entire coding tasks rather than just suggesting lines of code.

What Changed:

• Updated the main download link to point directly to version 2.3.
• Replaced simple code snippets with a complex "PyTorch MNIST Experiments" demo showing an AI agent planning and writing multiple files.
• Added "Thought" blocks to the demo to show how the AI reasons through problems before coding.
• Updated the "Codebase Understanding" section to highlight specific search actions like grepping and model-based searching.
• Added timestamps and status indicators (e.g., "Ready for Review") to the project sidebar in the demo.
