Viertes Analog-Profil neben den SM2135EH-Lampen: PWM-Kanaele R=PB13 (ch1), G=PB16 (ch2), B=PB15 (ch3) bei 800 Hz, PIN-belegt aus der Original-Firmware (qcl_build_config_lamp.h, HARDWARE_MOBL_LED_SHIELD). Kein CW/WW-Zweig: ct_min == ct_max ist das Erkennungszeichen fuer 'weiss = RGB-Mischung', nl_color.c gibt in diesem Fall alle drei Farbkanalgleich. Neues Bauziel in allen Skripten; test_release zaehlt Dateizahlen jetzt aus TARGETS statt hart 8/16.
