chore: update v.mod version

- Clarify that Windows requires gcc (tcc does not support .a static library format)
- Add separate build commands for macOS/Linux and Windows
- Document pre-compiled library locations by platform
- Add w64devkit as recommended MinGW download option

+# V-Hono Benchmark
+
+Performance benchmarks for V-Hono web framework.
+
+## Framework Comparison (500 connections, 100K requests)
+
+| Framework | RPS | Errors | Avg Latency | P50 | P95 | P99 |
+|-----------|-----|--------|-------------|-----|-----|-----|
+| **v-hono (uSockets)** | **20,231** | **0** | **24.62ms** | **23.65ms** | **33.82ms** | **57.29ms** |
+| v-hono (picoev) | 16,177 | 0 | 30.75ms | 26.25ms | 35.37ms | 111.38ms |
+| veb (V官方) | 7,278 | 772 | 68.06ms | 55.79ms | 71.62ms | 98.90ms |
+
+### Performance Summary
+
+- **v-hono (uSockets) vs veb**: **2.78x faster**, zero errors
+- **v-hono (uSockets) vs picoev**: **25% faster**, better P99 latency
+- **v-hono (picoev) vs veb**: **2.22x faster**, zero errors
+
+## Running Benchmarks
+
+### 1. Start Test Server
+
+**uSockets backend:**
+```bash
+v -enable-globals -cc gcc -ldflags "-ldbghelp" benchmark/usockets_server.v -o server.exe
+./server.exe
+```
+
+**Picoev backend:**
+```bash
+v -enable-globals examples/picoev_example.v -o server.exe
+./server.exe
+```
+
+### 2. Run Integration Tests
+
+```bash
+go run benchmark/usockets_verify.go
+```
+
+### 3. Run Performance Tests
+
+```bash
+# 200 connections, 100K requests
+go run tests/main.go -url "http://127.0.0.1:9998" -c 200 -n 100000
+
+# 500 connections, 100K requests
+go run tests/main.go -url "http://127.0.0.1:9998" -c 500 -n 100000
+```
+
+### 4. Quick Concurrent Test (PowerShell)
+
+```powershell
+powershell -File benchmark/quick_test.ps1
+```
+
+## Test Files
+
+| File | Description |
+|------|-------------|
+| `usockets_server.v` | uSockets test server with full API |
+| `usockets_verify.go` | Go integration test (17 test cases) |
+| `quick_test.ps1` | PowerShell concurrent test script |
+| `../tests/main.go` | Go performance benchmark tool |
+
+## Test Coverage
+
+The integration test (`usockets_verify.go`) covers:
+
+- ✅ Basic GET routes (root, health, static)
+- ✅ Dynamic routes (single/multi/nested params)
+- ✅ Query parameters
+- ✅ Response formats (JSON, HTML, custom status)
+- ✅ HTTP methods (POST, PUT, DELETE)
+- ✅ Error handling (404)
+- ✅ Keep-Alive connections
+- ✅ Throughput performance

+# v-hono 高并发优化指南
+
+## 概述
+
+v-hono 使用 uSockets 作为高性能网络后端，经过优化后可以稳定支持 **10,000+ 并发连接**。
+
+## 性能测试结果
+
+| 并发数 | RPS | 平均延迟 | P99延迟 | 成功率 |
+|--------|-----|----------|---------|--------|
+| 5,000 | 81,524 | 60.77ms | 295.17ms | 100% |
+| 6,000 | 56,290 | 98.46ms | 557.47ms | 100% |
+| 7,000 | 42,895 | 130.04ms | 824.80ms | 100% |
+| 8,000 | 30,537 | 165.27ms | 1058.05ms | 100% |
+| 9,000 | 28,693 | 215.86ms | 1422.67ms | 100% |
+| 10,000 | 24,198 | 240.90ms | 1602.10ms | 100% |
+
+测试环境：macOS (Apple Silicon M3 Max)
+
+**重要提示**：每次测试后需等待 60 秒让 TIME_WAIT 连接释放，否则会影响下一次测试结果。
+
+## 关键优化
+
+### 1. uSockets backlog 参数
+
+原始 uSockets 库的 `listen()` backlog 参数硬编码为 512，限制了高并发能力。
+
+**修复位置**：`v-hono/usockets/src/bsd.c` (第 532 行和第 578 行)
+
+```c
+// 修改前
+listen(listenFd, 512)
+
+// 修改后
+listen(listenFd, 16384)
+```
+
+修改后的源码保存在 `v-hono/usockets/src/bsd.c`，编译后的库文件在 `v-hono/lib/libusockets_full.a`。
+
+**重新编译**：运行 `v-hono/usockets/build.sh` 脚本。
+
+### 2. 系统参数配置
+
+macOS 需要调整以下系统参数：
+
+```bash
+# 查看当前值
+sysctl kern.ipc.somaxconn
+
+# 临时修改（重启后失效）
+sudo sysctl -w kern.ipc.somaxconn=8192
+
+# 永久修改（添加到 /etc/sysctl.conf）
+kern.ipc.somaxconn=8192
+```
+
+**注意**：实际 backlog 值会被 `kern.ipc.somaxconn` 截断，所以系统参数也需要相应调整。
+
+## 重新编译 uSockets（可选）
+
+如果需要自定义 backlog 值，可以重新编译 uSockets：
+
+```bash
+# 1. 克隆 uSockets
+git clone https://github.com/uNetworking/uSockets.git
+
+# 2. 修改 src/bsd.c 中的 listen 调用
+# 将 listen(listenFd, 512) 改为 listen(listenFd, 16384)
+
+# 3. 编译（macOS with libuv）
+WITH_LIBUV=1 CFLAGS="-I/opt/homebrew/include" make
+
+# 4. 复制到 v-hono
+cp uSockets.a /path/to/v-hono/lib/libusockets_full.a
+
+# 5. 重新编译 v-hono 应用
+v -enable-globals -prod -o your_app your_app.v
+```
+
+## 使用建议
+
+1. **生产环境**：建议使用 uSockets 后端（`app.listen_usockets(port)`）
+2. **系统调优**：确保 `kern.ipc.somaxconn` >= 8192
+3. **文件描述符**：服务器和客户端都需要设置 `ulimit -n 65535`
+4. **启动命令**：`ulimit -n 65535 && ./your_server`
+
+## 高并发测试
+
+运行高并发测试：
+
+```bash
+# 启动服务器
+ulimit -n 65535 && ./bench_server_usockets
+
+# 运行测试 (5000-10000 并发)
+ulimit -n 65535 && go run v-hono/tests/test_high_concurrency.go
+
+# 单独测试某个级别
+ulimit -n 65535 && go run v-hono/tests/test_high_concurrency.go 8000
+```
+
+## 问题排查
+
+如果高并发测试失败，检查：
+
+1. 服务器是否正常响应：`curl http://localhost:8080/health`
+2. 系统参数：`sysctl kern.ipc.somaxconn`
+3. 文件描述符限制：`ulimit -n`
+4. 测试客户端是否有端口耗尽问题
+
+## 版本信息
+
+- uSockets backlog: 16384
+- 测试日期: 2026-01-03
+- 测试通过最大并发: 10,000（不使用渐进式启动）

+// SSE Streaming Demo - Server-Sent Events Example for v-hono
+// This example demonstrates all SSE streaming helper functions:
+// - stream() - Basic binary streaming
+// - stream_text() - Text streaming
+// - stream_sse() - Server-Sent Events streaming
+//
+// Run with: v -enable-globals run examples/sse_demo.v
+// Then open a browser and navigate to http://127.0.0.1:3000
+// Or use curl to test the endpoints:
+//   curl http://127.0.0.1:3000/stream
+//   curl http://127.0.0.1:3000/stream-text
+//   curl http://127.0.0.1:3000/sse
+//
+// Features demonstrated:
+// - Basic binary streaming with stream()
+// - Text streaming with stream_text()
+// - SSE event streaming with stream_sse()
+// - Error handling with custom error handlers
+// - SSE event fields (data, event, id, retry)
+// - Multi-line data in SSE events
+// - Sleep/delay between stream writes
+// - onAbort callback for client disconnection
