Summary: Cursor adds advanced PyTorch experiment framework

Why It Matters: This change shows Cursor is making its AI coding tools better for complex machine learning tasks.

What Changed:

• The "PyTorch MNIST Experiments" section was greatly expanded with new code and descriptions.
• The code now includes mixed precision training, validation splits, and a configuration system.
• The demo text for "PyTorch MNIST Experiments" changed from "Generating" to "Done, configurable MNIST experiment framework with AMP and reports."
• The "In Progress" count for tasks changed from 4 to 3 in one section, and "Ready for Review" changed from 2 to 3 in another.
• A new section was added at the end of the content, which appears to be a changelog discussion about direct linking for changelog entries and Node.js version updates.
