/**

|
* @file load_const.c
|
|
* @brief Implements the OP_LOAD_CONST opcode for loading constants in the VM.
|
|
*
|
|
* This file handles the OP_LOAD_CONST instruction, which loads a constant value
|
|
* from the bytecode's constant pool onto the stack.
|
|
*
|
|
* Behavior:
|
|
* - operand is index into constant pool
|
|
* - Pushes copy of constant onto stack
|
|
*
|
|
* Error Handling:
|
|
* - Exits if invalid constant index
