Detailed Description

Implements OP_PROC_RUN to execute a shell command and capture stdout.

Behavior:

• Pops command (string); runs it via the platform shell; pushes a map {"out": string, "code": int}.
• "code" is the process exit status if available, otherwise -1.

Errors:

• On allocation failures or popen errors, returns {out: "", code: -1}.
