pedrosanto90/.dotfiles_v2 ? reverse-engineered prompt

Build me a complete dotfiles and installer setup for Debian 13 Stable that turns a plain install into a minimalist, keyboard first Sway desktop. I want it to set up a clean Wayland login, start Sway automatically after I sign in, and include the usual day to day tools like a launcher, status bar, notifications, terminal, shell, tmux, Neovim, screenshots, clipboard history, file manager, Bluetooth, audio, network, VPN, and power management.

Please make it safe to run more than once, and if it finds existing config files, back them up instead of overwriting them. I also want a dark Tokyo Night look across the whole setup, with matching themes for the terminal, editor, bar, and GTK apps, plus a simple way to switch between light and dark.

Use the repo contents to wire everything together, and make the installer handle the software that needs special setup, like Ghostty, Neovim, Node, Go, Docker, and the browser and other desktop apps. Keep it Debian 13 only, and if you need to check current install details online, go ahead.
