Detailed Description

Implements the OP_LTE opcode for less-than-or-equal comparison in the VM.

This file handles the OP_LTE instruction, which checks if the first value is less than or equal to the second. The values are popped from the stack, and the result (1 or 0) is pushed back.

Behavior:

• Pops two values from the stack.
• Checks if the first value is less than or equal to the second.
• Pushes 1 (true) or 0 (false) onto the stack.

Error Handling:

• Exits with an error if the operands are of incompatible types.

Example: // Bytecode: OP_LTE // Stack before: [42, 42] // Stack after: [1]
