Detailed Description

Implements the OP_AND opcode for logical AND in the VM.

This file handles the OP_AND instruction, which performs a logical AND operation on two boolean values. The values are popped from the stack, and the result is pushed back.

Behavior:

• Pops two boolean values from the stack.
• Performs a logical AND operation.
• Pushes the result (1 or 0) onto the stack.

Error Handling:

• Exits with an error if the operands are not boolean values.

Example: // Bytecode: OP_AND // Stack before: [1, 0] // Stack after: [0]
