Macro for creating tasks with less boilerplate

Examples

// Minimal - anonymous task with Normal priority
let task = task!(|ctx| {
    // task body
    Ok(())
});

// With name only (Normal priority)
let task = task!("my_task", |ctx| {
    // task body
    Ok(())
});

// With name and priority
let task = task!("my_task", High, |ctx| {
    // task body
    Ok(())
});

// With priority only (anonymous task)
let task = task!(Low, |ctx| {
    // task body
    Ok(())
});

// With move semantics (works with all patterns)
let captured = 42;
let task = task!("my_task", move |ctx| {
    println!("Captured: {}", captured);
    Ok(())
});
