feat(vd960Loop): 看门狗升级双保险喂狗模式 + 超时对齐 V4B(1.64s)

对照 DLD154V4B V2.10(同款 AT32F421):
- 原直喂模式缺 ISR 活性检测: TMR15 ISR 死但主循环活 -> 看门狗永不复位(假活)
- 升级: TMR15 ISR 5ms 递增 g_wdg_counter + 主循环 poll_wdg() 500ms 才 reload
- 超时 3s(div64/rld1875) -> 1.64s(div16枚举/rld4095)
- wdt_feed 定义移至 TaskLoop.c 改名 poll_wdg, 与 V4B 同构
- 修正 main.c 注释矛盾(4687 vs 1875); 沿用 WDT_CLK_DIV_16 枚举写法避免
  V4B 同源传值 bug
- 隔离测试 3 项断言全过(分频16/超时1638ms>500ms/10s喂20次/ISR死不喂)
