/**
* @file arr_push.c
* @brief Implements the OP_ARR_PUSH opcode for appending elements to arrays in the VM.
*
* This file handles the OP_ARR_PUSH instruction, which appends a value to the end of an array.
* The array and value are popped from the stack, and the new length of the array is pushed back onto the stack.
*
* Behavior:
* - Pops the value and array from the stack.
* - Appends the value to the end of the array.
* - Pushes the new length of the array onto the stack.
*
* Error Handling:
* - Exits with an error if the array is of the wrong type.
* - Exits with an error if memory allocation fails during the append operation.
*
* Example:
* // Bytecode: OP_ARR_PUSH
* // Stack before: [42, [10, 20, 30]]
* // Stack after: [4]
*
