ScottW514 7c45642f05 image.health: the watchdog's proof is WDOG1's own WCR, not the sysfs state
The sysfs state of watchdog0 says whether a process holds the device, and
none does: the kernel's core feeds the boot-armed hardware. The check
reads WCR through /dev/mem (WDE set, a 60 s period) and expects the state
to read inactive. Bench: PASS on image 20260903003213 with WCR 0x771f. The
BRINGUP facts bullet says the same.
