//! AxVCpu - Virtual CPU abstraction for ArceOS hypervisors.
//!
//! This crate provides a unified, architecture-independent interface for managing virtual CPUs
//! in hypervisor environments. It delegates architecture-specific operations to implementations
//! of the `AxArchVCpu` trait while providing common functionality like state management,
//! CPU binding, and execution control.
//!
//! # Features
//!
//! - Architecture-agnostic virtual CPU management
//! - State machine for VCpu lifecycle (Created → Free → Ready → Running)
//! - Per-CPU virtualization state management
//! - Hardware abstraction layer for hypervisor operations
//! - Support for interrupt injection and register manipulation
