Extended Candle fork: FFT ops, interactive notebooks, and development playground

[springyworks]

Hey Candle community! 👋

Been exploring and extending the Candle workspace - thought this might be useful as a reference for some additions and experiments.

What's been added:

• FFT & Scan Operations: Extended implementations with CPU/GPU support and testing
• Interactive Notebooks: Added Rust-native Jupyter notebooks for tensor exploration and algorithm demos
• Tensor Visualization: Built egui-based display helpers for real-time tensor feedback and debugging
• Build Consistency: Resolved some WASM example conflicts and addressed a few clippy warnings
• Development Tools: Enhanced xtask utilities and documentation
• Exploration Playground: Added 0aEXPLORATION area for prototyping and experimentation

The approach:

This represents an "additive exploration" - building on the solid foundation you've created to experiment with new features and development patterns. The changes are extensive but experimental, not suitable for direct contribution.

On the workflow: AI-assisted development

Full transparency: Lots of the work was done with AI assistance. Effective for rapid prototyping, but required careful oversight for quality and coherence.

Reference value:

The fork serves as an experimental branch - useful for seeing one approach to extending tensor operations or understanding patterns for workspace organization.

Curious what others think about the approaches taken here - especially around the FFT and asssociative scan implementations and development tooling!
