chore: v1 整理 — 清理历史文件、DDL 合并、文档归档

- 清理 1155 个已删除的历史文件（废弃 prompt_logs、tmp、旧 ops 脚本）
- export/ 数据文件从 git 移除（已在 .gitignore）
- demo-miniprogram 从 tmp/ 移入 apps/，添加 CLAUDE.md 注解
- DDL 合并：完整 schema 定义填充到 db/*/schemas/（从 docs/database/ddl/ 复制）
- 39 个 v1 迁移脚本归档到 db/_archived/migrations_v1_merged/
- 4 个迁移变更类 BD_Manual 文档归档到 docs/database/_archived/
- .gitignore 补充 .vite/ 和 apps/*.zip
- settings.json 添加 effortLevel 默认配置
- scripts/ops/ 新增运维脚本入库
