M0+M1: 基建 + 用户/密钥/核心代理

后端 (Go/Gin/GORM):
- 配置(viper+env)、SQLite/Postgres 迁移、argon2id、AES-GCM 渠道密钥、JWT+refresh cookie
- 用户注册/登录/刷新/登出、API Key CRUD(仅存哈希、明文一次展示)
- 代理网关: /v1/chat/completions、/v1/responses、/v1/models 直通 OpenAI 渠道
  非流式+流式(SSE 零缓冲转发), 用量捕获(chat 末块/responses completed 嵌套),
  OpenAI 错误格式(401/402/404/502), 余额检查
- 异步批量记账 + 余额流水 + 日聚合, admin 用户/余额/配置 API
- 单测: crypto/jwt/apikey/流式 usage 提取

前端 (Vue3+TS+Vite+Tailwind v4):
- taste-skill 设计 tokens: 深色仪表盘, 石墨+信号铜色, Outfit+JetBrains Mono
- Landing/登录/注册, 控制台(仪表盘图表/密钥管理/用量明细)
- 基础组件 Button/Input/Badge/Modal, ECharts 用量图

部署: docker-compose(nginx+api+postgres), 双 Dockerfile, nginx SSE 反代
联调: scripts/mockupstream 本地 mock 上游, 端到端验证通过
