Function jit_rebox_array_int 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn jit_rebox_array_int(
    vec_ptr: *mut LustInt,
    vec_len: usize,
    vec_cap: usize,
    array_value_ptr: *mut Value,
) -> u8

Rebox Vec back to Array Value IMPORTANT: Writes the specialized vec data back into the EXISTING Rc<RefCell<Vec>> This ensures the original array is updated, not replaced
