Extract PropertyResolver strategy

[henriquemoody]

Previously, the resolution of validators from property types and explicit new resolution strategies required editing the class, and a class-typed property annotated with #[Attributes] was validated twice — once by the explicit-attribute branch and again by the declared-type branch — which tripped the circular-reference guard on the second pass.

This commit moves that responsibility to a dedicated PropertyResolver interface with composable implementations, so each strategy can be developed and composed independently. The composite collapses duplicate Attributes entries, ensuring each property is validated exactly once even when multiple resolution paths produce the same instance. The Attributes class is reduced to its single responsibility, and resolver chains become pluggable through the constructor.

Pull request overview

This PR refactors Respect\Validation\Validators\Attributes by extracting “which validators apply to a property” into a dedicated PropertyResolver strategy interface with composable implementations, aiming to make resolution extensible and to avoid duplicate nested validation (notably around #[Attributes] + declared class types).

Changes:

• Introduces PropertyResolver plus DeclaredTypePropertyResolver, ExplicitAttributePropertyResolver, and CompositePropertyResolver.
• Updates Attributes to accept an injectable resolver chain and to delegate property-validator discovery to it.
• Adds unit tests and new test stubs to cover the new resolution strategies and composite de-duplication behavior; updates docs and the dev lint command exclusions.
