K1C CFS without official Creality firmware: CFS protocol client and Klipper integration

K1C CFS without official Creality firmware reconstructs part of the Creality CFS RS-485 control protocol so a K1C running a community Klipper stack can operate the filament box. Its Python client and Klipper extension cover discovery, addressing, sensors, RFID, filament feed and retraction; the combined toolchange macro remains unfinished.
