- 新建 ScriptModel (packages/adapters/sqlalchemy_impl/models.py)
  字段: id, user_id(indexed), title, content, segments(JSON), tags(JSON), created_at, updated_at
- 新建 script_service.py: CRUD 封装，用户隔离，tag 筛选，分页
- 新建 schemas/script.py: Pydantic request/response schemas
- 新建 routes/scripts.py: RESTful API (GET/POST/PUT/DELETE /api/v1/scripts)
- 新建 alembic 070_add_scripts_table.py: scripts 表 + user_id 索引
- 注册路由到 router.py (prefix=/scripts, tag=ScriptLibrary)
- 35 单元测试: service 15 + schema/route 20
