feat(vhost): 虚拟主机/多站点支持

- cocoon.h: 新增 cocoon_vhost_t 结构体和 COCOON_MAX_VHOSTS 宏
- config.c: JSON 解析器新增 vhosts 数组解析
- server.c: HTTP/1.1 请求根据 Host 头匹配虚拟主机 root_dir
- http2.h/c: HTTP/2 根据 :authority 匹配虚拟主机,存储为 Host 头
- http2.c: 新增 http2_session_set_server_config() API
- cocoon.json: 添加 vhosts 配置示例
- tests: 新增 3 项虚拟主机集成测试
- 编译零警告,142 单元测试 + 106 集成测试全部通过

2. ~~连接池 HTTP/1.0 兼容~~ ✅ 2026-06-09
- 后端发送 Connection: close 时正确关闭连接而非归还
3. **HTTP/2 代理流式转发** — 当前为非流式(先收集完整响应),未来改为流式
4. 虚拟主机 / 多站点 — 低优先级
4. ~~虚拟主机 / 多站点~~ ✅ 2026-06-09 — 基于 Host 头匹配HTTP/1.1 + HTTP/2 均支持
5. 主动健康检查 — 后台线程定期探测后端(当前为被动式)
## 最近行动记录
- 2026-06-09 15:00: **虚拟主机 / 多站点支持**
- `cocoon.h`: 新增 `cocoon_vhost_t` 结构体(`server_name[256]` + `root_dir[512]``cocoon_config_t` 新增 `vhosts[COCOON_MAX_VHOSTS]``num_vhosts`
- `config.c`: JSON 解析器新增 `vhosts` 数组解析,每个对象支持 `server_name``root_dir` 字段
- `server.c`: 新增 `vhost_match_root_dir()` + `conn_get_host()` 辅助函数
- `handle_request()` 中解析请求后根据 Host 头匹配虚拟主机,使用对应的 `root_dir` 提供静态文件服务
- `http2.h`: `http2_session_t` 新增 `server_config` 指针(用于虚拟主机匹配)
- `http2.c`: 新增 `http2_session_set_server_config()` API`vhost_match_root_dir()` 辅助函数
- `on_header_callback()`: `:authority` 伪头不再忽略,存储为 `Host` 普通头供匹配使用
- `http2_serve_static()` / `http2_serve_post()`: 根据 stream 的 Host 头匹配虚拟主机根目录
- `server.c`: 所有 HTTP/2 会话创建点h2c 直接连接、Upgrade 升级、TLS ALPN均调用 `http2_session_set_server_config()`
- `cocoon.json`: 示例配置添加 `vhosts` 数组示例
- `tests/integration_test.sh`: 新增 3 项虚拟主机集成测试
- `site-a.local` → 返回 Site A 内容
- `site-b.local` → 返回 Site B 内容
- `unknown.local` → 回退到全局默认内容
- 编译零警告142 个单元测试 + 106 项集成测试全部通过
- 提交已推送到 `main`
- 2026-06-09 12:00: **连接池 HTTP/1.0 兼容 + 配置合并 bug 修复**
- `proxy.c`: `proxy_relay_backend()` 中新增 `connection_closed` 标志
- 当 `recv() == 0`(后端关闭连接)时标记 `connection_closed = true`

feat(healthcheck): 新增主动健康检查模块
- 新增 healthcheck.c / healthcheck.h 模块
- 每个后端支持独立配置探测路径(默认 /health、间隔默认 5s、超时默认 2s
- 使用线程 + sleep 实现周期性探测
- 探测成功/失败更新后端 healthy 状态,与现有被动检测共用状态字段
- 配置 JSON 新增 healthcheck 字段path, interval_ms, timeout_ms, enabled
- 优雅启动/关闭server_create 启动探测线程server_destroy 停止并 join
- 编译零警告
- 142 单元测试 + 103 集成测试全部通过(新增 4 项健康检查测试)
