Add claude-desktop, Anthropic's Linux desktop beta

Anthropic ships the Claude desktop app for Linux only through its own
Debian repository, so the package repacks the deb the way
openai-codex-desktop does: extract data.tar.xz, replace the bare
/usr/bin symlink with a launcher that asks Chromium for Wayland
directly, and keep the vendor copyright as the license.

Updates come through the declarative "debian" upstream provider: the
apt Packages index names the newest version, and the per-architecture
pool debs are hashed when one appears. Verified by pinning 1.44121.2
and watching bin/sync-upstream rewrite it back to 1.46388.2
byte-identically.
