Pull request overview

This pull request adds a new PHPStan rule ExposePublicPropsShouldBeFalseRule to enforce that Twig components explicitly set exposePublicProps: false in the #[AsTwigComponent] attribute. This promotes explicit control over which properties are exposed to Twig templates, improving security and maintainability of Symfony UX Twig components.

Key Changes:

• Adds new PHPStan rule that validates the exposePublicProps parameter in #[AsTwigComponent] attributes
• Includes comprehensive test coverage with fixtures for various scenarios
• Adds documentation to README following the established pattern for rule documentation

The tip message "Add" is misleading when exposePublicProps is already set to true. Consider using "Set" instead of "Add" to cover both cases (when the parameter is missing and when it's set to true).

Suggested change:

->tip('Set "exposePublicProps" to false in the #[AsTwigComponent] attribute.')

Suggested change

	->tip('Add "exposePublicProps: false" to the #[AsTwigComponent] attribute.')
	->tip('Set "exposePublicProps" to false in the #[AsTwigComponent] attribute.')
