Initial commit: NexusOS project + desktop theme baseline
Captures the known-good state after theme consolidation and consistency reconciliation: - NexusOS GTK/xfwm4/icon theme assets (assets/themes, management/Mint-Y-Nexus) - Tightened right-click menus, visible separators, no menu icons - assets/themes/install-theme.sh: idempotent restore of all wiring (symlinks, xfconf xsettings+xfwm4, GTK 3/4 settings.ini) - .gitignore excludes venv/ollama/models/runtime/db Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
