- _decode_odometer: catch all exceptions and return None instead of raising. PID 0xA6 (odometer) is not guaranteed on 2013 Toyota Yaris — a garbage response or unsupported PID previously raised ValueError through python-obd's decoder, which app_obd._query() caught and treated as a lost connection, killing the entire OBD session. Now it gracefully returns None. - connect_obd: reset all sensor globals (rpm, coolant_temp, fuel_level, throttle_position, mil_on, dtc_codes, odometer, timestamps) on each new connection so the UI doesn't display stale readings from the previous ignition cycle while fresh polls are completing. - yaris-obd.service: add commented OBD_PROTOCOL=6 hint for post-confirmation pinning (eliminates 3-5s auto-probe delay after first confirmed connection).
