Update flake inputs and flake.lock to Nix/nixpkgs and home-manager release 25.11; bump home.stateVersion and setup script NIXOS_RELEASE. Migrate git config to new Home Manager layout (programs.git.settings, aliases under settings.alias), adjust delta config path, and reorganize SSH into matchBlocks with enableDefaultConfig=false to avoid global leaks. Simplify snapd session variable handling to avoid recursion. Misc: tweak Dashy title, replace du-dust->dust and plex-media-player -> plex-desktop, remove unused hostname arg, and add GitHub Copilot instructions document.
