fix(keybinds): SUPER+? bind uses base keysym slash, not question

Item 32. Item 26 added SHIFT to the modmask but kept the shifted keysym
`question`, so the bind stayed dead. Hyprland 0.55 resolves a bind's
keysym with SHIFT consumed (issue #7750, behaviour since 0.43): with
Shift held, `$mod SHIFT, question` is matched against `slash` and never
fires. The base keysym is what works — same pattern as this file's own
`$mod SHIFT, 1` workspace binds. Also updates rofi.nix prettyKeys to
collapse "SHIFT + /" → "?" so the cheatsheet row still reads "SUPER + ?".

Verified: V0 `nix flake check --no-build` green; V1 HM activation built,
built hyprland.conf carries `bind=$mod SHIFT, slash, exec, nomarchy-menu
keybinds` (kb_layout=us → slash is `?`). The keypress opening the menu is
V3 — queued (HARDWARE-QUEUE, existing SUPER+? entry updated).

+## 2026-07-08 — SUPER+? cheatsheet re-fixed: base keysym (iteration #65, item 32)
+- **Task:** BACKLOG item 32 — SUPER+? still didn't open the cheatsheet
+  after item 26's fix. Re-diagnose.
+- **Did:** Root cause = wrong keysym, not path/rofi. Hyprland 0.55 resolves
+  a bind's keysym with SHIFT *consumed* (issue #7750, since 0.43), so
+  `$mod SHIFT, question` looks for `slash` and never matches. Item 26 fixed
+  the modmask but kept the shifted keysym → still dead. Changed keybinds.nix
+  `question` → `slash` (the BASE keysym, exactly like the working
+  `$mod SHIFT, 1` workspace binds in this same file); updated rofi.nix
+  prettyKeys collapse `SHIFT + /` → `?` so the cheatsheet still reads
+  "SUPER + ?". Dispatch (`nomarchy-menu keybinds`) confirmed already fine.
+- **Verified:** V0 `nix flake check --no-build` green. V1: HM activation
+  built; grepped the built hyprland.conf → `bind=$mod SHIFT, slash, exec,
+  nomarchy-menu keybinds` (beside the proven `$mod SHIFT, 1`), `kb_layout=us`
+  confirms slash→? ; `nix eval` of prettyKeys → "SUPER + ?".
+- **Pending:** V3 — the keypress actually opening the menu is invisible
+  below hardware (that's how item 26 slipped); the existing HARDWARE-QUEUE
+  "SUPER+? opens the cheatsheet" entry updated to the slash fix.
+- **Next suggestion:** Bernardo's two live requests — (1) fold the provided
+  power-menu mockup into item 36(b) [design now in hand]; (2) right-align a
+  keybind hint on every menu/submenu row that has one.
