Vijay Janapa Reddi 6622bb226c Fix module test execution pattern with if __name__ == '__main__' guards ...

This change ensures tests run immediately when developing modules but don't execute when modules are imported by other modules.

Changes:
- Protected all test executions with if __name__ == "__main__" blocks
- Unit tests run immediately after function definitions during development
- Module integration test (test_module()) runs at end when executed directly
- Updated module-developer.md with new testing patterns and examples

Benefits:
- Students see immediate feedback when developing (python module_dev.py runs all tests)
- Clean imports: later modules can import earlier ones without triggering tests
- Maintains educational flow: tests visible right after implementations
- Compatible with nbgrader and notebook environments

Tested:
- Module 01 runs all tests when executed directly ✓
- Importing Tensor from tensor_dev doesn't run tests ✓
- Cross-module imports work without test interference ✓
