Detailed Description

Implements the OP_KEYS opcode for retrieving map keys in the VM.

This file handles the OP_KEYS instruction, which retrieves the keys of a map and pushes them as an array onto the stack.

Behavior:

• Pops the map from the stack.
• Retrieves the keys of the map.
• Pushes the keys as an array onto the stack.

Error Handling:

• Exits with an error if the map is of the wrong type.

Example: // Bytecode: OP_KEYS // Stack before: [{"a": 1, "b": 2}] // Stack after: [["a", "b"]]
