charge_control_end_threshold was written (80) but charge_types stayed
[Adaptive], which ignores the cap while still reporting it — battery
kept charging past 80% on Latitude. Oneshot now selects Custom when a
limit is set, Adaptive/Standard when off; sets start hysteresis; doctor
warns if type ≠ Custom while limited.
V0: flake check --no-build green. V3: re-apply limit, confirm
charge_types shows [Custom] and status stops Charging above cap.
