wangfq ef3316f2b3 docs(vd960DBN): BLE 日志查询交互过程文档 + 协议 V1.01 动态分包 + 周期心跳 
- 新增 docs/DLD960_BLE日志查询交互.md: 0x25/0x26/0x27 完整交互示例
  (真实日志逐字节解析, 分包规则, 第二分包未发问题记录)
- DLD960_BLE协议.md V1.01: 分包上限改为随协商 MTU 动态 (min(MTU-9,94))
- peripheral.c: performPeriodicTask 加 500ms 心跳打印 (确认 TMOS 周期存活
  + resp 队列状态, 定位第二分包为何不续传)
