Detailed Description

Implements OP_SOCK_RECV to receive data from a socket into a string.

Behavior:

• Pops max_len (int) and fd (int); attempts to read up to max_len bytes; pushes a string with the bytes read.
• On EOF or error, pushes empty string. Non-UNIX platforms return empty string (unsupported).

Errors:

• If argument types are wrong, prints an error and pushes empty string.
