Added cargo command aliases, and cfg target for Windows

[GreasySlug]

If compiling with cargo, long commands need to be typed, but this allows execution with short commands. If you prefer some other alias name, please give me some suggestions.

Threads are used for windows, but this is not necessary for Unix/Linux. So, use cfg to target Windows only.

It seems that only Ubuntu is supported, so please can I request Windows support? https://docs.github.com/ja/actions/using-github-hosted-runners/about-github-hosted-runners#supported-runners-and-hardware-resources

cfg!(windows) doesn't ignore platform dependencies. In the future, when writing low-level processes such as read and terminal, dependencies will be required for each platform. It is a good idea to write processes that take this into account now.

The code below is not good, but it works.

#[cfg(target_os = "windows")]
fn main() {
    const STACK_SIZE: usize = 4 * 1024 * 1024;

    let child = thread::Builder::new()
        .stack_size(STACK_SIZE)
        .spawn(run)
        .unwrap();

    // Wait for thread to join
    child.join().unwrap();
}

#[cfg(not(target_os = "windows"))]
fn main() {
    run();
}

It seems to fail to build on Ubuntu.

Thanks!
