Detailed Description

Implements OP_FD_SET_NONBLOCK to toggle O_NONBLOCK on a file descriptor.

Behavior:

• Pops on (int, 0/1) and fd (int); sets or clears O_NONBLOCK via fcntl; pushes 1 on success, 0 otherwise.
• On non-UNIX platforms, returns 0 (unsupported).

Errors:

• If types are wrong, prints an error and returns 0.
