feat(waybar): #63 generated bar logo + powermenu

Add custom/nomarchy (left, Nomarchy monogram → nomarchy-menu) and
custom/powermenu (right → nomarchy-menu power) to the generated bar so
default-theme users match whole-swap affordances. Pin font-family:
Nomarchy; use literal UTF-8 glyphs (Nix has no \u escapes).

Verified: V2 (THEME=tokyo-night theme-shot — monogram + power glyph).
Close #63.

+## 2026-07-10 — #63 generated Waybar logo + powermenu
+- **Task:** NEXT #63 — reverse parity: generated bar lacked whole-swap
+  logo → menu and power icon → power menu.
+- **Did:** `custom/nomarchy` (left, Nomarchy.ttf U+F000) + `custom/powermenu`
+  (right, U+F011 → `nomarchy-menu power`) in generated settings/style.
+  Fixed Nix `\uf000` pitfall (no `\u` escapes — use literal UTF-8).
+  Whole-swaps already had both; no JSON/CSS edits. Closed #63.
+- **Verified:** **V2** — `THEME=tokyo-night` theme-shot: left monogram N,
+  right power glyph, accent styling; config modules-left/right correct.
+  Crop paths under `/tmp/theme-shot-tn2-*.png`.
+- **Next suggestion:** product path #55 fingerprint menu (or #57 live install).
