Detailed Description

Implements the OP_LOAD_GLOBAL opcode for loading global variables in the VM.

This file handles the OP_LOAD_GLOBAL instruction, which loads a global variable onto the stack using its index.

Behavior:

• Loads the global variable at the specified index.
• Pushes the value onto the stack.

Error Handling:

• Exits with an error if the index is out of bounds.

Example:

• Bytecode: OP_LOAD_GLOBAL 0
• Stack before: []
• Stack after: [global_value]
