Pull request overview
This PR implements process execution functionality for the hardened_std library, enabling the init process to execute whitelisted binaries like nvidia-smi, nvidia-ctk, and other GPU-related utilities. The implementation follows a security-hardened model with compile-time binary whitelisting and static string constraints.
Changes:
- Implemented Command builder pattern with spawn(), status(), and exec() methods
- Added Child process management with wait() and kill() functionality
- Created binary whitelist enforcement with separation of production and test binaries
- Implemented Stdio redirection supporting Null, Inherit, Piped, and Fd variants
