* fix: force stdin to Stdio::null for all user code execution (#6575)

Set stdin to Stdio::null for all Commands that execute user code across all supported languages to prevent unwanted input consumption. This affects Python, Deno, Bash, PowerShell, Go, Rust, PHP, Ruby, Java, C#, Ansible, Nu, and Bun executors.

The dedicated worker handler was intentionally left unchanged as it requires stdin for inter-process communication.
