This commit introduces two new commands to the `borg` CLI: - `borg compile`: Compiles a `Borgfile` into a "Terminal Isolation Matrix" (`.matrix` file). The `Borgfile` format is a simple text file with `ADD <src> <dest>` instructions. - `borg run`: Executes a `.matrix` file using `runc`. The command unpacks the matrix into a temporary directory and then executes `runc run`. Tests have been added for both commands, mocking the `runc` execution to avoid environment dependencies.
