wandering1 7feeea6c56 实现独立看门狗:CubeMX 配置 IWDG + 任务心跳位图,恢复三处被覆盖定制
经 CubeMX 图形界面启用 IWDG(Prescaler=64 / Reload=1249,标称 2498ms /
最坏 1701ms),并落地心跳位图判定、各任务埋点、RCC_CSR 复位原因上报与
configASSERT 改造。重生成覆盖的既有定制已全部恢复。

P0(开机死循环):HAL_IWDG_Init() 内部立即启动看门狗,而 CubeMX 把
MX_IWDG_Init() 插在 app_main_init() 之前——该段 NAND/RTC/ADC 初始化耗时
数秒无喂狗点,按 2.5s 超时必然复位。改 Src/iwdg.c 为只填参数不启动,
启动移交 task_wd_start(),由 defaultTask 在存储 bring-up 完成后调用。

恢复的三处定制(重生成覆盖):
- Src/stm32f4xx_it.c:HardFault_Handler 崩溃现场采集被打回空 while(1)
- Inc/FreeRTOSConfig.h:栈溢出检测与堆失败钩子两个宏被整块删除
- Src/freertos.c:三处任务栈实测记录中文注释丢失(数值未丢)

新增:
- App/util/task_watchdog.{c,h}:心跳位图 + 抽样判定 + IWDG 延后启动
- time_sync.c 长等待切片:net_recv_to 单次可睡满 30s 预算,切成 200ms 片
- Src/main.c 复位原因锁存(读后即清 RMVF,防残留误判)

埋点:defaultTask(唯一喂狗者)/ netTask(含 PHY 等待循环)/ uiTask /
timeSyncTask。ftpTask 首期剔除掩码,待二期改 lftpd。

门禁:build 0 错误 0 警告;pre-commit 10 钩子全通过;Flash +2956B / RAM +40B。
