Detailed Description

Implements the OP_PCSC_TRANSMIT opcode (conditional build).

Transmits an APDU to the connected smart card associated with a given handle. Returns a map with the response bytes and status words. When PCSC support is disabled at build time, consumes its arguments and returns a map with code = -2.

OP_PCSC_TRANSMIT: (handle_id:int, apdu:array<int>) -> map

Pops: apdu array, then handle_id.
Pushes: map { data: array<int>, sw1:int, sw2:int, code:int }.
- On success (code == SCARD_S_SUCCESS), data contains response bytes (no status words) and sw1/sw2 are the trailing status bytes.
- On error, data is [], sw1/sw2 remain -1, and code is the PCSC error.
Notes: Negotiates protocol from the connected handle (T0/T1) and uses SCardTransmit. APDU bytes are taken modulo 256 from array ints.
