feat(backend): 搭建 FastAPI 分层骨架 — 配置加载 / 健康检查 / SQLAlchemy+Alembic 就位
- uv 工程(Python 3.12,pyproject + uv.lock,dev: pytest/ruff) - 分层包结构:api / application / domain / infrastructure / quant(qlib_adapter) / agent / core - app.core.config:加载根 config.yaml + .env,sqlite 相对路径解析到项目根 data/ - SQLAlchemy Base + Session 工厂(Infrastructure 层,业务走 Repository) - Alembic 迁移环境就位(env.py 复用应用配置,render_as_batch 兼容 SQLite) - GET /api/health + pytest 冒烟 6 项通过 / ruff clean / uvicorn 启动验证
