refactor(data): 重构交易所适配器，修复 Kline 实体复合主键

- 废弃旧 adapter 体系 (base/binance/types.ts)，新增 base_rest/rest.ts
  基于 Binance 官方 SDK 实现 REST K 线拉取
- Kline 实体改为四列复合主键 (exchange/symbol/interval/time)，
  修复单列 time PK 导致的跨 symbol 写入冲突
- 新增 filterConsecutive()：K 线连续性过滤，首缺口截断策略
- 新增 service/kline.ts：批量 UPSERT K 线入库
- 新增 types/ 共享类型定义、example/ 示例、run/ 运行脚本
