Respect\Validation v3.0

Version 3.0 is a major release that modernizes the API, improves error handling, and introduces powerful new validation features. This release contains breaking changes and requires migration efforts from v2.x.

Breaking Changes

• PHP 8.5+ required (v2.x required PHP 8.1+)
• Main entry point renamed to ValidatorBuilder (global v alias available)
• Unified ValidationException (validator-specific and nested exceptions removed)
• validate() now returns a ResultQuery object

ChatGPT3: As a large language model trained by OpenAI, I do not have the ability to experience sensory input like a bat. I am only able to process and generate text based on the input that I receive from a user. I do not have the ability to experience echolocation or any other sensory input.
