Module ostd 

OSTD-like (OS Trusted Domain) abstraction layer for Strat9-OS

This module provides a minimal, auditable unsafe code base that abstracts hardware operations behind safe interfaces. Inspired by Asterinas OSTD.

Design concept

• Minimal TCB: only essential unsafe code lives here
• Safe Abstractions: all public APIs are safe wrappers
• Hardware Traits: platform-independent interfaces
• Confined Unsafe: all unsafe blocks are justified with SAFETY comments
