Detailed Description

Implements the OP_STORE_GLOBAL opcode for storing global variables in the VM.

This file handles the OP_STORE_GLOBAL instruction, which stores a value into a global variable using its index.

Behavior:

• Pops the value from the stack.
• Stores the value into the global variable at the specified index.

Error Handling:

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

Example:

• Bytecode: OP_STORE_GLOBAL 0
• Stack before: [42]
• Stack after: []
