feat: complete P0/P1/P2 — WebUI SPA, OpenClaw sidecar+simulator, healthcheck auto-sched+perf

P0: WebUI重构
- 完整 SPA 仪表盘 (7标签页), //go:embed dashboard.html
P1: OpenClaw兼容 (三通道: SKILL.md / sidecar / simulator)
- Node.js 模拟进程统一加载任意 OpenClaw 插件
- JSON-RPC 2.0 over stdio 协议, go:embed 内嵌
P2: Healthcheck 优化
- 定时自动执行 (startAutoCheck, 30min)
- healthcheck_perf 性能监控工具

其他: agentcli/cmd 插件, integration_test, status.go,
      test_deepseek 清理, 多项 bug 修复
