Detailed Description

Implements the OP_SLICE opcode for array slicing in the VM.

This file handles the OP_SLICE instruction, which creates a new array containing elements from the original array between specified start and end indices.

Behavior:

Pops end index, start index, and array from the stack
Creates a new array containing elements from start to end-1
Pushes the new array onto the stack

Error Handling:

Exits with error if arguments are wrong types
Handles negative indices and out-of-bounds cases gracefully

Example: // Bytecode: OP_SLICE // Stack before: [3, 1, [10,20,30,40]] // Stack after: [[20,30]]
