/**
* @file apop.c
* @brief Implements the OP_APOP opcode for removing elements from arrays in the VM.
*
* This file handles the OP_APOP instruction, which removes the last element from an array
* and pushes the removed element onto the stack. The array is popped from the stack.
*
* Behavior:
* - Pops the array from the stack.
* - Removes the last element from the array.
* - Pushes the removed element onto the stack.
*
* Error Handling:
* - Exits with an error if the array is of the wrong type.
* - Exits with an error if the array is empty.
*
* Example:
* // Bytecode: OP_APOP
* // Stack before: [[10, 20, 30]]
* // Stack after: [30]
*
