feat(home): switch launcher/menu from fuzzel to rofi 2.0

rofi 2.0 landed in nixpkgs 26.05 with native Wayland (mainline upstreamed
the lbonn rofi-wayland fork — `wayland enabled`), so the original reason
to prefer fuzzel (rofi being X11-only / needing a community fork) is gone.
rofi's `.rasi` is far more expressive than fuzzel's flat INI, which lets
the launcher be a proper themed hero surface and revives the legacy
per-theme launcher designs.

- modules/home/rofi.nix replaces fuzzel.nix: per-element theme generated
  from theme-state.json (accent border, highlighted selection, rounded
  inputbar) via lib.formats.rasi.mkLiteral; themes/<slug>/rofi.rasi
  whole-swap; the nomarchy-menu dispatcher re-pointed to `rofi -dmenu`
  (power/theme/clipboard/calc with -mesg/files/web + root picker).
- SUPER+D is now `rofi -show drun`; the menu binds are unchanged.
- nomarchy.fuzzel.enable → nomarchy.rofi.enable; fuzzel dropped from
  home.packages. Pango handles nf-glyph fallback (no explicit font list
  needed as fuzzel's fcft did). show-icons off until an icon theme ships.

Verified: flake check green, HM generation builds, the generated
theme.rasi parses under `rofi -dump-theme`, Hyprland config verifies.
Not verified: rofi's on-screen rendering needs a real session.

Docs: README menu/override/roadmap sections and the module tree updated;
the per-theme launcher roadmap item now points at porting the legacy
rofi.rasi designs (the whole-swap mechanism is in place).

 - **Theme parity with legacy:** summer-day/night now carry their legacy
   bar layouts as `waybar.jsonc` whole-swaps (adapted: dead legacy script
   modules dropped, Nerd-Fonts-v2 codepoints remapped to FontAwesome/v3,
   logo button opens nomarchy-menu); the other four identity themes are
   palette recolors and already match. Remaining: a visual pass over all
   six on the live ISO
-- **Per-theme fuzzel identity:** the `themes/<slug>/fuzzel.ini` whole-swap
-  mechanism ships; what remains is authoring the inis for the six identity
-  themes from their legacy rofi.rasi files (per-element colors like
-  summer-night's green inputbar aren't expressible in fuzzel's flat
-  scheme — approximate, note the rest as a renderer limitation)

+  mechanism ships; what remains is porting the legacy `rofi.rasi` designs
+  (summer-day/night already have them in the legacy branch) for the
+  identity themes — rofi's `.rasi` expresses their per-element looks
+  (green inputbar, inverted window) directly, unlike the old flat scheme
 - **Faster switches:** move `backgrounds/` out of the flake source (the 86 MB
   re-copy on every state write is the main eval tax), then pre-built theme
   variants if still needed
