Detailed Description

Implements the OP_NOT opcode for logical NOT in the VM.

This file handles the OP_NOT instruction, which performs a logical NOT operation on a boolean value. The value is popped from the stack, and the result is pushed back.

Behavior:

• Pops a boolean value from the stack.
• Performs a logical NOT operation.
• Pushes the result (1 or 0) onto the stack.

Error Handling:

• Exits with an error if the operand is not a boolean value.

Example:

• Bytecode: OP_NOT
• Stack before: [0]
• Stack after: [1]
