- Python package stemroller/ -> stemify/, Android package com.stemroller.mobile -> com.stemify.mobile, app names, QML module, icons, desktop entries, MPRIS and Plex product names - Done-markers are now .stemify.json; stemd renames the old ones once at startup so songs separated before the rename aren't separated again - A top-level README covering the server, the Android and Android Auto app, the EQ, Stem Now and the desktop apps Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
