Introduce worker threads for VirtIO Console and RNG devices, enabling asynchronous operations and improving device responsiveness. Refactor device structures for better state encapsulation and pipelining support.

Remove `Deloxide` deadlock detection, add clippy lint suppressions, and improve formatting consistency throughout the project.

Remove asynchronous functionality from `runner` and `handlers`. Refactor code to simplify execution flow and improve performance. Clean up `Cargo.lock` by removing unused dependencies and `tokio`-related crates.

Migrate `nvmm/vcpu` to `system/vmachine` module structure and refactor `Vcpu` for hypervisor-agnostic backend support. Enhance MMIO handling and implement `build.rs` for initrd generation. Update `Cargo.toml` dependencies.
