refactor(core): 从 libbox 迁移到 box.New() 直接 API

移除 libbox CommandServer/Client gRPC 架构，Service 直接持有
*box.Box 实例。PlatformIO 直接实现 adapter.PlatformInterface，
桌面/mobile 通过 isMobile 字段分支。移除事件回调系统，改为
Query 轮询模式。删除 handler.go、callback.go 及旧设计文档。

 ### Capabilities
 
 - **Service lifecycle** — init, start, stop, destroy with hot-reload support
-- **Config management** — validate, reload, TUN restart, VPN split-tunneling
+- **Config management** — validate, reload TUN, VPN split-tunneling
 - **Proxy control** — node selection, URL test delay, routing mode switch
-- **Real-time events** — traffic, logs, connections, proxy groups, mode changes via callback
-- **Connection tracking** — full lifecycle with per-connection metadata
+- **Query API** — proxies, traffic, logs, connections, memory stats via JSON
 - **Platform IO** — TUN fd, socket protector, WiFi state (mobile)
 - **Resource monitoring** — memory stats, goroutines, OOM protection
