Commands previously inherited stdin from the parent bash shell
(a pipe for script input), causing hangs when they attempted
to read stdin for TTY detection or interactive prompts.
Redirecting to /dev/null ensures commands receive EOF
immediately, enforcing non-interactive behavior and preventing
indefinite hangs.
Applies to both foreground (exec) and background
(execStream/startProcess) execution modes.
