This commit adds two new Go programs to the `examples` directory to demonstrate how to use the `pkg/matrix` and `pkg/datanode` packages programmatically: - `examples/create_matrix_programmatically`: Shows how to create a `.matrix` file from scratch. - `examples/run_matrix_programmatically`: Shows how to unpack and execute a `.matrix` file using `runc`. The `examples` directory has been reorganized to place each runnable example in its own subdirectory, which is the standard Go practice for handling multiple `main` packages.
