feat: v0.3.1 — Go/Gin 后端重写 + gh-ost 集成
架构变更: - Python/FastAPI → Go/Gin 重写（Python 后端保留在 backend-python/） - GORM + SQLite（兼容现有数据库表结构） - JWT 认证 + RBAC 权限中间件 Go 后端结构: - cmd/server/main.go — 入口，端口 9000 - config/config.go — 环境变量配置 - internal/model/ — GORM 模型（30张表，完全兼容 SQLite） - internal/handler/ — auth/instance/ticket/dashboard/ghost handler - internal/middleware/ — JWT 认证 + CORS - internal/ghost/ — gh-ost 集成模块（同步/异步执行，任务管理） - router/router.go — API 路由注册（/api/v1/...） gh-ost 集成: - RunGhOst() 同步执行 - RunGhOstAsync() 异步执行 + 进度追踪 - TaskManager 管理多个并发任务 - API: POST /ghost/dry-run, /ghost/execute, GET /ghost/status/:taskId 核心 API 已对齐: - POST /auth/login (JWT) - GET /dashboard/stats, /dashboard/my-tickets - GET /tickets/statistics, CRUD + approve/execute - GET/POST/PUT/DELETE /instances - GET /users, /audit-rules, /announcements, /settings 已验证: - 登录 admin/admin123 ✅ - Dashboard 99工单/110查询/4实例 ✅ - 工单统计按角色过滤 ✅
