How it works

• The binary runs and there's no CHILD_APP_ENV_VAR environment variable ⇾ no user code runs, only the GUI is displayed.
• The "Run" button in the GUI is pressed ⇾ CHILD_APP_ENV_VAR is set, the binary is started again. Arguments are passed to stdin and stdout is intercepted for displaying output.
• The binary is run with CHILD_APP_ENV_VAR ⇾ the user-provided closure is run.
