Clean up repository
- Remove stale feature branches (kept debugging branch with unmerged work)
- Move test_spatial_core.py to correct directory (tests/09_spatial)
- Remove .tito user state from tracking (config.json, progress.json)
- Delete archived CLI commands (tito/commands/_archived/)
- Move standalone integration tests to tests/integration/
- Remove outdated audit/report markdown files
- Remove old template and deprecated test files
- Simplify .gitignore for .tito/ directory

Add MSEBackward and organize comprehensive test suite
New Features:
- Add MSEBackward gradient computation for regression tasks
- Patch MSELoss in enable_autograd() for gradient tracking
- All 3 loss functions now support autograd: MSE, BCE, CrossEntropy
Test Suite Organization:
- Reorganize tests/ into focused directories
- Create tests/integration/ for cross-module tests
- Create tests/05_autograd/ for autograd edge cases
- Create tests/debugging/ for common student pitfalls
- Add comprehensive tests/README.md explaining test philosophy
Integration Tests:
- Move test_gradient_flow.py to integration/
- 20 comprehensive gradient flow tests
- Tests cover: tensors, layers, activations, losses, optimizers
- Tests validate: basic ops, chain rule, broadcasting, training loops
- 19/20 tests passing (MSE now fixed!)
Results:
✅ Perceptron learns: 50% → 93% accuracy
✅ Clean test organization guides future development
✅ Tests catch the exact bugs that broke training
Pedagogical Value:
- Test organization teaches testing best practices
- Gradient flow tests show what integration testing catches
- Sets foundation for debugging/diagnostic tests
