Detailed Description

Implements the OP_INDEX_SET opcode for array and map assignment in the VM.

This file handles the OP_INDEX_SET instruction, which assigns a value to an element in an array or a key in a map.

Behavior:

• Pops the value, index/key, and container from the stack.
• For arrays, assigns the value to the specified index.
• For maps, assigns the value to the specified key.

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_SET
• Stack before: [42, 1, [10, 20, 30]]
• Stack after: [[10, 42, 30]]
