Detailed Description

Implements the OP_PCSC_DISCONNECT opcode (conditional build).

Disconnects a previously connected smart-card handle and frees the corresponding registry slot. When PCSC support is disabled at build time, this opcode returns 0 after consuming its argument.

OP_PCSC_DISCONNECT: (handle_id:int) -> int

• Pops: handle_id.
• Pushes: 1 on success; 0 on error (invalid id/not found) or when disabled.
• Notes: Uses SCardDisconnect(..., SCARD_LEAVE_CARD).
