Erik SimonandClaude Sonnet 4.6 e6c6685d96 terra: flatpak, unstable packages, GTK dark theme, comms workspace
- nix-flatpak input; discord, telegram, qbz as Flathub flatpaks; removes
  qbz and proton-pass-cli flake inputs
- proton-pass-cli and claude-code from nixpkgs-unstable via extraSpecialArgs
- dconf color-scheme = prefer-dark replaces per-session gsettings call
