1//! Inter-Process Communication (IPC) subsystem for VeridianOS
2//!
3//! This module implements high-performance IPC mechanisms including:
4//! - Synchronous message passing with < 5μs latency
5//! - Asynchronous channels for streaming
6//! - Zero-copy shared memory transfers
7//! - Capability-based security integration
