Detailed Description

Implements the OP_CLEAR opcode for clearing arrays in the VM.

Handles the OP_CLEAR instruction, which removes all elements from an array. The array is popped from the stack; the opcode pushes an integer result (currently 0) as an acknowledgement.

Behavior:

• Pops the array from the stack.
• Clears all elements from the array (array becomes empty in place).
• Pushes 0 (integer) to acknowledge success.

Error Handling:

• Exits with a runtime error if the operand is not an array.

Example:

• Bytecode: OP_CLEAR
• Stack before: [[10, 20, 30]]
• Stack after: [0]
