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.

-- **fastfetch branding:** legacy ships an ASCII-art logo
-  (`core/branding/logo.txt` on the legacy branch) intended as the fastfetch
-  image. Vendor it, resize to a sensible terminal width, and color it from
-  the palette (accent), then wire a `fastfetch` config that uses it. (No
-  fastfetch config in v1 yet.)
-- **Nomarchy logo font in Waybar:** legacy's `core/branding/Nomarchy.ttf`
-  is a glyph font whose logo codepoint was used as the Waybar main-menu
-  button (e.g. the summer-night bar). Vendor the font, install it, and set
-  the `custom/nomarchy` button's `format` to that glyph (currently `󱄅`, a
-  Nerd Font icon) so the button shows the real Nomarchy mark.
+- ✓ **fastfetch branding:** `modules/home/fastfetch.nix`
+  (`nomarchy.fastfetch.enable`) — the vendored vector logo, recolored to
+  the palette accent and rendered to compact block-art via chafa at build
+  time (tracks the theme), fronting a curated module list. Replaces the
+  oversized legacy ASCII with a themed, sized logo.
+- ✓ **Nomarchy logo font in Waybar:** vendored `Nomarchy.ttf`
+  (`modules/nixos/branding/`), installed via `fonts.packages`, and the
+  summer-day/night menu buttons now use its `U+F000` glyph with
+  `font-family: Nomarchy` pinned in their CSS (Nerd Fonts also occupy
+  U+F000, so the pin is required). The other themes have no logo button.
+- **Quality-of-life command aliases:** assemble a curated collection of
+  shell aliases/abbreviations for common operations (git, nix, navigation,
+  the nomarchy helpers, …), themed into the zsh shell experience
+  (`modules/home/shell.nix`). Decide scope and which to ship on by default.
 - **Theme-switch feedback:** ✓ the "rebuilding…" notification is now
   persistent (timeout 0) and replaced in place by "applied ✓" / failure
   via a synchronous tag, so a multi-minute switch never reads as a failed
