+> Renamed Interface → StreamInterface throughout alknet-core. Added MessageInterface trait with InterfaceRequest/InterfaceResponse types. Added HttpInterface and DnsInterface stubs. Restructured InterfaceConfig into StreamInterfaceConfig + MessageInterfaceConfig. Added StreamInterfaceKind and MessageInterfaceKind enums. Restructured ListenerConfig from flat struct to enum with Stream/Http/Dns variants per ADR-035. Removed TransportKind::Dns (DNS is a MessageInterface). Changed TransportKind::WebTransport from { host: String } to { server_name: Option<String> }. Updated all import sites, pairs.rs, serve.rs, server/handler.rs, napi/serve.rs, lib.rs, and all tests. 415 tests pass, clippy clean, fmt clean.
