Detailed Description

Implements the OP_RETURN opcode for returning from a function in the VM.

This file handles the OP_RETURN instruction, which returns from the current function and optionally pushes a return value onto the stack.

Behavior:

• Pops the optional return value from the stack.
• Returns to the caller frame.
• Pushes the return value onto the stack (if any).

Error Handling:

• Exits with an error if the frame stack is empty.

Example: // Bytecode: OP_RETURN // Stack before: [42] // Stack after: [42]
