MiddlewareAttributeScanner

Reflects a list of candidate classes for #[Middleware] attributes and builds the MiddlewareDefinitions that MiddlewareOrderResolver sorts into a pipeline order.

Modeled on Quiote\Routing\Compiler\AttributeRouteScanner, but takes an explicit FQCN list rather than globbing directories: unlike actions (which always live under a module’s Actions/ tree), middleware has no established directory convention to scan, so candidates are whatever the framework’s own core list plus MiddlewareCatalog::getAttributedCandidates() supply.

A class is only a candidate for scanning if it’s already been supplied by the caller — this scanner never does its own class discovery. Classes without a #[Middleware] attribute, or that don’t implement MiddlewareInterface, are silently skipped (the same “presence is opt-in” rule AttributeRouteScanner uses for #[Route]).
