orgchain: Super Testnet restyled for lineage (lineage.yolopreneur.lol/orgchain/)

Skin and copy only: src/lineage.css over style.css with lineage's tokens, a rehearsal guide and lineage branding,
relative paths (base './'), the theme follows the system under its own key, and Inscriboor downloads link to
supertestnet.lol (the extension only connects there). Unit tests 32/32; checked in Chrome at 1280 and 390 wide,
light and dark, through a full root → birth → recursive inscription run with no CSP or script errors.
