v0.1.2 of auris

A Flutter UI kit and Material 3 theme with a warm amber-on-near-black, chamfered sci-fi aesthetic — a drop-in ThemeData plus a library of custom HUD widgets. Changelog excerpt: - Use absolute raw.githubusercontent.comURLs for the README gallery images. pub.dev does not render README-relative image paths (it strips them), so the gallery rendered blank on the package page even after the repository URL was corrected.
