Overview

Validates option objects using constraint-based validation

The Validator class applies a collection of constraints to an options object, ensuring all validation rules are satisfied before execution.

This is a proper OOP validator that:

  • Uses constraint objects (not procedural code)

  • Returns validation result objects (not string arrays)

  • Provides clear separation of concerns
