feat: 三种部署方式 — embed单容器 + 二进制部署 + K8s

新增三种部署方式（原有 docker-compose 不受影响）:

1. Docker embed 单容器 (docker-compose.embed.yml):
   - go:embed 前端嵌入后端二进制
   - 不需要 nginx 容器，3容器→2容器
   - 镜像仅 54.8MB (vs 原来 1.16GB)
   - 用法: make docker-embed

2. 二进制部署 (deploy/binary/):
   - make build-binary 生成单二进制
   - install.sh 自动创建 systemd 服务
   - 适合无 Docker 环境
   - 用法: scp aiops + install.sh, bash install.sh install

3. Kubernetes 部署 (deploy/k8s/):
   - devops 命名空间全套 yaml
   - MySQL StatefulSet + Redis StatefulSet + Backend Deployment
   - ConfigMap + Secret + Ingress
   - 用法: kubectl apply -f deploy/k8s/

核心改动:
- backend/cmd/embed.go: go:embed 前端 + SPA fallback 路由
- backend/Dockerfile.embed: 四阶段构建 (前端→后端embed→agent→runtime)
- Makefile: build-binary + docker-embed 目标
- deploy/README.md: 四种部署方式对比文档
