stylix: full migration off matugen

Flips stylix.autoEnable on so every supported target picks up colours
from the wallpaper-derived base16 palette, and tears out the per-app
matugen plumbing it replaces:

- fred.nix: drop the matugen config.toml block and the .keep files;
  move btop and ghostty to programs.* with the colour-bearing options
  removed (stylix owns those).
- gnome.nix: remove the matugen and jq packages, the hand-written
  gtk.css home.file overrides (replaced by gtk.gtk{3,4}.extraCss layered
  on top of stylix's theme), the WallpaperShell user-themes override,
  and the gtk-theme/cursor-theme/accent-color dconf entries that stylix
  now writes.
- stylix.nix: add a home.activation hook that recolours Adwaita folder
  SVGs using stylix.colors.base0D and pulls in Papirus mimetypes —
  same outcome as the old matugen post-hook but driven by stylix.
- common.nix: drop the matugen invocation from the `update` alias.

Leftover matugen-only behaviour intentionally dropped: Vesktop CSS,
the GNOME accent hue-mapping, the VSCodium colour-merge (stylix's
vscode target handles that natively). Templates in templates/ are kept
on disk for now; can be removed in a follow-up.
