fix(keybinds): SUPER+? never fired — shifted keysym needs SHIFT in the modmask

? is typed as Shift+/, so Hyprland saw mods SUPER+SHIFT with keysym
`question` and the exact-modmask match skipped the `$mod, question`
bind — the keypress fell through to the focused window (caught on the
Latitude, BACKLOG item 26; the menu itself was fine from a terminal).

- keybinds.nix: bind is now `$mod SHIFT, question`.
- rofi.nix prettyKeys collapses "SHIFT + ?" back to "?" so the
  cheatsheet row keeps the documented SUPER + ? label.
- MEMORY.md gotcha: shifted keysyms need SHIFT in mods — invisible to
  eval-tier tests.

Verified: V0 (flake check --no-build); V1 both surfaces (eval'd
settings.bind renders `$mod SHIFT, question, exec, nomarchy-menu
keybinds`; built nomarchy-menu's cheatsheet renders `SUPER + ?`).
V3 queued: SUPER+? on the Latitude after home-update + relogin.
