Fix per-key RGB: correct pixel-lookup, chain-length, effect config

Browse source 
- pixel-lookup: column-by-column snake per foostan Corne v1.1 PCB diagram
- chain-length=27 in keymap (fork shield overlay overrides to 10)
- EFF_START=4 (layer indicators), ON_START=y, AUTO_OFF_IDLE=n
- Document per-key RGB in README with LED chain order and usage
