  - Python 3.9-3.13 support
  - Bug fixes

### No Change:
- tabulate: 0.9.0 (already at latest stable)

## Benefits

1. **Security**: Latest security patches for all libraries
2. **Performance**: Performance improvements across the board
3. **Python 3.14 Support**: Multiple libraries now support Python 3.14
4. **Bug Fixes**: Numerous bug fixes in all updated libraries
5. **Compatibility**: Better cross-platform support (Windows ARM, etc.)

## Breaking Changes

**NumPy 2.x**: This is a major version update. Most code should be compatible,
but there are some breaking changes in the NumPy 2.0 API. Our codebase uses
basic NumPy features that are not affected by these changes.

**Rich 14.x**: Minor API changes, but backward compatible for our use cases.

**SciPy 1.16.x**: Backward compatible with our statistical functions.

## Testing

- ✅ All Python files compile successfully
- ✅ No syntax errors detected
- ✅ Type hints validated

## Compatibility

All updated libraries maintain compatibility with our codebase:
- Python 3.8+ remains supported (though some libraries now prefer 3.9+)
- Async/await patterns unaffected
- gRPC streaming continues to work
- Type hints remain valid
