feat(hyprland): launch-or-focus binds (item 17)

nomarchy.launchOrFocus (opt-in, commented template example): each
entry gives a key that FOCUSES the app's existing window
(case-insensitive class match via jq + a "(?i)" focuswindow regex) or
launches it when none is open. One shared nomarchy-focus-or-launch
script; a bind whose command was removed from the suite fires a
"not installed" toast instead of failing silently. The same entries
render into the SUPER+? cheatsheet through prettyKeys — bind and
documentation stay one source. README row added.

Verified: V0; V1 — a scratch downstream with two entries renders both
binds (default command = lowercased class; custom mods/command/desc
honored), the script passes bash -n with a usage guard, and the
cheatsheet carries both rows. Focus behaviour needs a session -> V3
(HARDWARE-QUEUE).

+- **Task:** BACKLOG NEXT#17 (the UI review is Bernardo-gated; back to
+  the queue head). Item deleted.
+- **Did:** nomarchy.launchOrFocus (listOf submodule: key/mods/class/
+  command/desc; opt-in, template example) → hyprland.nix generates
+  binds through a shared nomarchy-focus-or-launch script (jq
+  case-insensitive class match → focuswindow "(?i)" regex, else
+  launch; uninstalled command → toast, so binds survive suite edits);
+  rofi.nix renders the same entries into the SUPER+? cheatsheet via
+  prettyKeys (single source). README row.
+- **Verified:** V0; V1 — scratch downstream with 2 entries: both
+  binds rendered (default command = lowercased class; custom
+  mods/command/desc honored), tool bash -n + usage exit 64,
+  cheatsheet rows present. Focus behaviour needs a session → V3
+  queued.
+- **Pending:** V3. Queue after this: #18 control center [big, needs
+  the form-factor Decision], #19 Look&Feel menu (gated on ≥3
+  entries), #20 [human], LATER tier.
+- **Next suggestion:** a QA sweep (#18/#19/#20 are blocked-ish) — or
+  item 19's precondition check (does Look & Feel earn 3 entries
+  yet?).
