Anthony Eid 592727b892 collab: Add request stream support (#56455) ... Adds streaming RPC forwarding to collab so guests can call `GetInitialGraphData` and `SearchCommits` against a remote host project. Previously these requests had no forwarder registered on the server and would fail when invoked by a guest. This mirrors the existing single-response forwarding pattern with new analogues: - `StreamResponse<R>` + `MessageContext::forward_request_stream` - `Server::add_request_stream_handler` - `forward_read_only_project_stream_request`, registered for both messages Also hardens both the unary and stream handlers to send `respond_with_error` when a handler returns `Ok` without sending/ending a response, so the client doesn't hang waiting for a reply that will never arrive. I added git graph collab integration tests for this as well.
