Pull request overview

Upgrades the project to Ruby 3.3.10 and modernizes the test/browser stack by removing PhantomJS/Poltergeist-era tooling in favor of Selenium + Chromium, while also applying RuboCop-driven refactors across library and specs.

Changes:

• Bump Ruby compatibility to >= 3.3.10 and update CI/Docker to run on modern Ruby + Chromium.
• Replace PhantomJS-based test setup with headless Chrome (Selenium/WebDriver) and update Watir/Capybara integrations accordingly.
• Apply broad formatting/refactor changes (frozen string literals, Ruby 3 idioms, RuboCop config/todo).
