Detailed Description

Implements OP_FD_POLL_WRITE to check if a file descriptor is writable.

Behavior:

• Pops timeout_ms (int) and fd (int); waits up to timeout for writability; pushes 1 if writable, 0 otherwise.
• On non-UNIX platforms, returns 0 (unsupported).

Errors:

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