Redundant info printed everytime a script is started

Each time a script is run using the RUN button redundant information is printed before and after

eg

```
MicroPython v1.26.1-dirty on 2025-10-07; Generic ESP32S3 module with ESP32S3
Type "help()" for more information.
>>>
raw REPL; CTRL-B to exit
>OKHello, MicroPython!
>
MicroPython v1.26.1-dirty on 2025-10-07; Generic ESP32S3 module with ESP32S3
Type "help()" for more information.
>>>
```

Expected would be only to print banner on start up, and on each script run only
```
Hello, MicroPython!
```

cf ESP32 MPY-Jama

Reproduce the behavior from the RUN button using the MicroPython ESP32 setup described in the issue, and trace where startup and script-run output are handled. Done means the startup banner appears once, while each subsequent run prints only the script output, such as "Hello, MicroPython!".
