rustnn v0.5.0 - Enhanced WebNN Integration

Summary

Version 0.5.0 brings enhanced WebNN integration, async execution support, and capability queries to rustnn. This release focuses on improving model format support and API ergonomics.

Major Features

WebNN Graph Integration

• Full (de)serialization support via webnn-graph crate
• Improved model format handling
• Better interoperability with WebNN ecosystem

Async Execution Support

• New dispatch() method for non-blocking tensor operations
• Implements W3C WebNN MLTensor explainer specification
• Enables efficient async workflows in Python

Capability Queries

• New op_support_limits() API to check backend capabilities
• Query supported operations, data types, and constraints
• Better error messages for unsupported features

Hugging Face Hub Integration

• Direct model loading from Hugging Face model hub
• Example demo included in repository
• Simplified model deployment workflow

Improvements

• Enhanced uint64 type support across all 85 operations
• Better error handling and validation messages
• Documentation updates with new examples
• Bug fixes for edge cases in shape inference
• Performance optimizations in ONNX converter

Python API Changes

New Methods

• MLContext.dispatch(graph, inputs, outputs) - Async execution (issue #3)
• ML.op_support_limits(device_type) - Capability queries (issue #1)

Improvements
