Release v4.0.1: Fix BlockRazor gRPC endpoints and set gRPC as default transport

## Changes since v4.0.0

### Bug Fixes
- Fixed BlockRazor gRPC endpoints to use correct gRPC service URLs
- Set gRPC as the default transport layer for BlockRazor with HTTP fallback

This release improves the reliability and performance of BlockRazor integration by prioritizing gRPC communication while maintaining HTTP fallback compatibility.

-### Changes
-
-- **Node1 QUIC support** — Node1 SWQOS can use QUIC transport: `SwqosConfig::Node1(api_token, region, custom_url, Some(SwqosTransport::Quic))`. Uses UUID auth on first bi stream, one bi stream per transaction, bincode-serialized `VersionedTransaction`. Region endpoints: `SWQOS_ENDPOINTS_NODE1_QUIC` (ny, fra, ams, lon, tk). New dependency: `uuid`.
-- **Speedlanding QUIC reliability** — Proactive connection check before send (`ensure_connected()`); 5s connect and send timeouts; reconnect uses `lock().await` so concurrent senders wait for the new connection instead of failing on `try_lock()`; TLS SNI is derived from the endpoint host (e.g. `nyc.speedlanding.trade`) with fallback to `speed-landing` for IP or unknown host. Addresses user reports of transactions failing to send.

+# Proto 生成的代码说明
+
+## 概述
+
+这个目录包含了从 `.proto` 文件预生成的 Rust 代码。
+
+## 文件说明
+
+- `serverpb.rs` - 从 `blockrazor.proto` 生成的 gRPC 代码
+  - 消息类型: `SendRequest`, `SendResponse`, `HealthRequest`, `HealthResponse`
+  - gRPC 客户端: `server_client::ServerClient`
+  - gRPC 服务端: `server_server::Server`
+
+## 用户使用
+
+用户**不需要**安装 `protoc` 或编译 proto 文件。这些代码已经预生成好了，可以直接使用。
+
+在 `blockrazor.rs` 中使用：
+```rust
+pub mod serverpb {
+    include!("pb/serverpb.rs");
+}
+```
+
+## 开发者如何重新生成代码
+
+如果你修改了 `.proto` 文件并需要重新生成代码：
+
+```bash
+cd sol-trade-sdk/proto/gen
+cargo run
+```
+
+这会在 `src/swqos/pb/serverpb.rs` 生成新的代码。
+
+## 技术细节
+
+生成工具使用 `tonic-prost-build` crate：
+- 输出目录: `src/swqos/pb`
+- Proto 文件: `proto/blockrazor.proto`
+- 生成工具: `proto/gen/`
+- 包含完整的客户端和服务端代码
