Detailed Description

Implements the OP_PCSC_LIST_READERS opcode (conditional build).

Lists available PC/SC reader names for a given context. On success returns an array of strings. When PCSC support is disabled at build time, returns an empty array after consuming its argument to keep the stack balanced.

OP_PCSC_LIST_READERS: (ctx_id:int) -> array<string>

Pops: ctx_id.
Pushes: array of reader names on success; empty array on error/disabled.
