Applied the datasheet-derived grouping rule to the ESP32-S3-WROOM-1-N8R2 terminals: all valid 41 datasheet pins now have Section, Pin Group, Pin Orientation, and Sub-symbol Designator Suffix assignments, and the duplicate out-of-range GND terminals were removed. I also updated the ESP32-S3-WROOM-1-N8R2 Pin Functional Groups project file with the applied rule summary.
