feat(branding): fastfetch logo + Nomarchy.ttf glyph in the Waybar button

Two branding follow-ups, using the vendored legacy assets:

- fastfetch (modules/home/fastfetch.nix, nomarchy.fastfetch.enable): the
  vector logo recolored to the palette accent and rendered to compact
  block-art via chafa at build time (so it tracks the theme), fronting a
  curated module list. Replaces the oversized legacy ASCII.
- Waybar logo glyph: vendor Nomarchy.ttf (modules/nixos/branding/),
  install it via fonts.packages, and switch the summer-day/night menu
  buttons to its U+F000 mark with `font-family: Nomarchy` pinned in CSS
  (Nerd Fonts also occupy U+F000, so the pin is required). Glyph stored as
  the  JSON escape for robustness.

Also log a roadmap item for a quality-of-life alias collection.

Verified: font family resolves as "Nomarchy" and the ttf maps U+F000;
both summer jsonc parse; chafa logo builds headless; nix flake check passes.
