Detailed Description

Implements the OP_REMOVE opcode for removing elements from arrays in the VM.

Handles the OP_REMOVE instruction, which removes an element from an array at the specified index. The array and index are popped from the stack; the removed element is pushed back onto the stack.

Behavior:

• Pops the index and array from the stack.
• Removes the element at the specified index from the array.
• Pushes the removed element onto the stack.

Error Handling:

• Exits with a runtime error if the container is not an array or index is not an int.
• Exits with a runtime error if the index is out of bounds.

Example:

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