bug(gop/build): If the dependent package already exists in the autogen file, gop run use old dependent package

[LiusCraft]

The following program sample.gop triggers an unexpected result

First execution:

source files:

1. project/main.gop

import "github.com/xxx/aaa/child"
println "Hello dfgdfgWorld"

child.HelloChild()

2. project/child/test.gop

package child
func HelloChild(){
    println "Hello Child 1"
}

3. project/go.mod

module github.com/xxx/aaa

go 1.21.5

Second execution:

change source files:

1. project/child/test.gop

package child
func HelloChild(){
    println "Hello Child 2"
}

Expected result

First execution：

> gop run .
Hello dfgdfgWorld
Hello Child 1

Second execution:

> gop run .
Hello dfgdfgWorld
Hello Child 2

Got

First execution：

> gop run .
Hello dfgdfgWorld
Hello Child 1

Second execution:

> gop run .
Hello dfgdfgWorld
Hello Child 1

Gop Version

gop v1.2.2 devel windows/amd64

Additional Notes

I tried to disable writing code under the go+ vscode plug-in and run it.

When it is executed for the first time, there is no autogen file, it will generate code, but it will not update the code when it is executed again.

This problem has always existed. In the past, it was difficult to find because the vscode plug-in would update the code.
