Subject: feat(filter): share platform req filter via Rc, drop clone_box

PlatformRequirementFilterInterface::clone_box (a todo!() trait-object
clone stub) is removed in favor of Rc<dyn ...> shared ownership, matching
PHP's by-reference sharing of the single filter object. Box<dyn ...> is
replaced with Rc<dyn ...> across the factory, Solver/RuleSetGenerator,
VersionSelector, AutoloadGenerator, Installer and the command layer
(BaseCommand/PackageDiscoveryTrait and their impls); clone_box call
sites become Rc clones.
