Vijay Janapa Reddi 902cd18eff feat: Complete NBGrader integration for all TinyTorch modules
Enhanced all remaining modules with comprehensive educational content:

## Modules Updated
-  03_layers: Added NBGrader metadata, solution blocks for matmul_naive and Dense class
-  04_networks: Added NBGrader metadata, solution blocks for Sequential class and forward pass
-  05_cnn: Added NBGrader metadata, solution blocks for conv2d_naive function and Conv2D class
-  06_dataloader: Added NBGrader metadata, solution blocks for Dataset base class

## Key Features Added
- **NBGrader Metadata**: All cells properly tagged with grade, grade_id, locked, schema_version, solution, task flags
- **Solution Blocks**: All TODO sections now have ### BEGIN SOLUTION / ### END SOLUTION markers
- **Import Flexibility**: Robust import handling for development vs package usage
- **Educational Content**: Package structure documentation and mathematical foundations
- **Comprehensive Testing**: All modules run correctly as Python scripts

## Verification Results
-  All modules execute without errors
-  All solution blocks implemented correctly
-  Export workflow works: tito export --all successfully exports all modules
-  Package integration verified: all imports work correctly
-  Educational content preserved and enhanced

## Ready for Production
- Complete NBGrader-compatible assignment system
- Streamlined tito export command with automatic .py → .ipynb conversion
- Comprehensive educational modules with real-world applications
- Robust testing infrastructure for all components

Total modules completed: 6/6 (setup, tensor, activations, layers, networks, cnn, dataloader)
