Detailed Description

Implements the OP_INDEX_GET opcode for array and map indexing in the VM.

This file handles the OP_INDEX_GET instruction, which retrieves an element from an array or a value from a map using an index or key.

Behavior:

• Pops the index/key and container from the stack.
• For arrays, retrieves the element at the specified index.
• For maps, retrieves the value associated with the specified key.
• Pushes the retrieved value onto the stack.

Error Handling:

• Exits with an error if the container is not an array or map, if the index/key is of the wrong type, or if the index is out of bounds.

Example:

• Bytecode: OP_INDEX_GET
• Stack before: [1, [10, 20, 30]]
• Stack after: [20]
