Created KNCM_settings.cfg with essential macros:
- CLEAN_NOZZLE: Wipe nozzle on brush/cloth
- SMART_PARK: Park nozzle at front for easy access
- LINE_PURGE: Print purge line at start
- Frame_Light_ON/OFF: Control frame LED (PD14)
- Part_Light_ON/OFF: Control part light (PD13)
Also added [output_pin] definitions for lights:
- frame_light: PD14
- part_light: PD13
This fixes: 'Unknown pin chip name rpi' error caused by
missing KNCM_settings.cfg include.
The file was previously included but didn't exist in the repo.
