Detailed Description

Implements the OP_CONTAINS opcode for checking array membership in the VM.

This file handles the OP_CONTAINS instruction, which checks if a value is present in an array. The value and array are popped from the stack, and a boolean result (1/0) is pushed back.

Behavior:

• Pops the value and array from the stack.
• Checks if the value is present in the array.
• Pushes 1 (true) or 0 (false) onto the stack.

Error Handling:

• Exits with an error if the array is of the wrong type.

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