fix(guard): consume the override sentinel as it's honored

One touch buys exactly one transaction. The maintenance console's forced live update sets the sentinel and clears it afterward, but a caller that dies mid-update would leave the file behind and keep the guard disarmed until reboot. The hook now deletes the sentinel at the moment it honors it, so a missed cleanup costs nothing. The env override is unchanged, and the caller's clear step stays as the belt-and-suspenders for transactions the hook never fires on.
