me-web? skeleton: Avalonia 12 app, server, packaging and CI

The first screen (online or not, a Check button, every language with a draft notice), the desktop and Android heads, the server's /api/info and /api/ip, a release tool that builds deb, rpm, a Windows exe, macOS zips, a signed APK and the server, and the Gitea workflows that run it. Rules adapted from passolo; AGPL-3.0. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_012CzABvBkbcFqoHdmi8b9WB
