ADR - convention router

[niden]

• Phalcon\Contracts\ADR\Router\Router + Phalcon\ADR\Router\Router - convention matcher: HTTP method + static path segments resolve the Action class, trailing segments become positional request attributes; match(RequestInterface) / RouterMatch unchanged. Config via setBaseNamespace() / setMiddlewareMap()
• Middleware resolved from a namespace-prefix map (group semantics); global middleware stays on the pipeline
• Removed the route table: Route, Group (contract + impl) and the HasMiddleware trait
• Phalcon\ADR\Responder\RedirectResponder - guard the instanceof behind a typeof == "object" check (was warning on every non-redirect result)
• Test fixtures under Phalcon\Tests\Support\ADR\Action\* (the matcher resolves real classes via class_exists)
