fix: clean up comments, unused docker and podman, etc

configuration.nix

  1. Removed stale NixOS boilerplate comments — all the default # Edit this
   configuration file..., # Bootloader., # Enable the X11 windowing
  system., # Define a user account..., commented-out options like #
  services.openssh.enable, firewall comments, and stateVersion comment
  2. Removed Docker/docker-compose — virtualisation.docker block,
  users.groups.docker, "docker" from extraGroups, docker-compose from
  systemPackages
  3. Removed vim from systemPackages
  4. Removed environment.variables.EDITOR (helix defaultEditor = true in
  home.nix handles this)
  5. Removed environment.sessionVariables.TERMINAL and
  environment.variables.RUSTICL_ENABLE (moved to home.nix)
  6. Removed /tmp/nix-build tmpfs mount
  7. Added networking.firewall.enable = true and # Required for Tailscale
  comment on checkReversePath
  8. Separated v4l2loopback from the RAM section (moved # RAM optimizations
   comment to above boot.kernel.sysctl)
  9. Fixed indentation — systemPackages, programs.appimage, imports, lists
  reformatted to one-item-per-line
  10. Trailing whitespace cleanup throughout

  home.nix

  1. Removed services.podman block
  2. Added TERMINAL = "kitty" and RUSTICL_ENABLE = "radeonsi" to
  home.sessionVariables
  3. Replaced 3 repetitive helix language blocks with a single map
  expression
  4. Formatting fixes — function args split to one-per-line, trailing
  whitespace, list formatting (categories, urls, etc.)
  5. Removed blank line before home.sessionVariables
