Detailed Description

Implements the OP_MAKE_ARRAY opcode for creating arrays in the VM.

This file handles the OP_MAKE_ARRAY instruction, which pops n values from the stack, creates an array from them, and pushes the resulting array back onto the stack.

Behavior:

• Validates the number of elements (n) to ensure it is non-negative and within stack bounds.
• Allocates temporary storage for the array elements.
• Constructs the array using make_array_from_values.
• Frees temporary storage and pushes the array onto the stack.

Error Handling:

• Exits with an error if n is invalid or if memory allocation fails.

Example: // Bytecode: OP_MAKE_ARRAY 3 // Stack before: [1, 2, 3] // Stack after: [[1, 2, 3]]
