* @file InstrMap.cpp
* @brief Spider VM instruction dispatch — array and switch implementations.
*
* AUTO-GENERATED by pygen.ipynb — DO NOT EDIT BY HAND.
*
* This file provides two equivalent dispatch mechanisms:
*
* 1. InstrMap[] — A lookup table of member-function pointers indexed by
* opcode. O(1) dispatch; suitable for platforms where
* indirect calls through function pointers are efficient.
*
* 2. CPU::execute(u16) — A switch/case over every opcode. Lets the
* compiler emit a jump table or branch tree; may be
* preferable on microcontrollers or when link-time
* optimisation can inline the handlers.
*
