Detailed Description

Implements the OP_INSERT opcode for inserting elements into arrays in the VM.

This file handles the OP_INSERT instruction, which inserts a value into an array at a specified index. The array, index, and value are popped from the stack, and the new length of the array is pushed back onto the stack.

Behavior:

Pops the value, index, and array from the stack.
Inserts the value into the array at the specified index.
Pushes the new length of the array onto the stack.

Error Handling:

Exits with an error if the array or index is of the wrong type.
Exits with an error if memory allocation fails during the insertion.

Example: // Bytecode: OP_INSERT // Stack before: [42, 1, [10, 20, 30]] // Stack after: [4]
