Detailed Description

Implements the OP_SET opcode for setting elements in arrays in the VM.

Handles the OP_SET instruction, which sets a value at a specified index in an array. The value, index, and array are popped from the stack; the value is returned back on the stack (as a copy) to mirror expression semantics.

Behavior:

Pops the value, index, and array from the stack.
Sets the value at the specified index in the array.
Pushes a copy of the value back onto the stack.

Error Handling:

Exits with a runtime error if the array or index is of the wrong type.
Exits with a runtime error if the index is out of bounds.

Example: // Bytecode: OP_SET // Stack before: [42, 1, [10, 20, 30]] // Stack after: [42]
