为什么：v2.0 代码侧已 ready，但 docker compose up 起来会立刻 panic
（表不存在），且密码硬编码、Binance 直连超时、无 healthcheck。
修复：
1. migrate init container（migrate/migrate:v4.18.1）
- depends_on postgres service_healthy 后执行
- 跑完 up 退出；app depends_on migrate service_completed_successfully
- 表不存在的 race 彻底消除
2. postgres healthcheck（pg_isready）
- interval 5s、retries 10、start_period 10s
- app 不再在 init 期连接失败
3. .env + .env.example（守卫 G9）
- 密码、端口、Binance URL 全部从环境变量读
- POSTGRES_PASSWORD 未设置时 docker-compose 直接报错退出（${VAR:?...} 语法）
- .env 已在 .gitignore，.env.example 留作模板
4. HTTP_PROXY/HTTPS_PROXY/NO_PROXY 透传
- 国内直连 fapi.binance.com 不稳（AGENTS.md §7.5）
- NO_PROXY 默认包含 postgres 容器名，避免本地代理误走
附加：config 卷只读挂载（防容器内意外写入）；ports 端口可由
.env 覆盖；postgres 容器名走 docker DNS（替换之前硬编码的
crypto-hermes-postgres）。
验证：python yaml lint 通过；依赖链 postgres healthy →
migrate completed → app start 已确认。docker 在本机不可用，
线上验证留给 commit 9 之后的人工 smoke。
