Splits channel construction into two files selected at compile-time via `if (dart.library.html)`: channel_factory_io.dart — native ClientChannel (HTTP/2) channel_factory_web.dart — GrpcWebClientChannel.xhr (HTTP/1.1) HubClient._channel is now `ClientChannelBase` so both implementations satisfy the same field type. dart:html-only imports (`package:grpc/grpc_web.dart`) stay isolated from the native compile path. Pairs with the hub-side `fai_grpc_web` adapter crate (fai/platform 0d07892) — `tonic-web` on the same port as native gRPC, so one `fai serve` listener handles both surfaces.
