Prepending us whenever the layout wasn't already us would have demoted
every Latin layout — de, fr, dk — to a secondary group, so those users
would have booted into a US layout they never asked for. Latin layouts
resolve the default keysym bindings fine, so only the layouts that can't
type Latin letters need us in front. That list already exists for the
initramfs hook, and a test keeps the two copies in sync.
Also match on the first layout rather than looking for us anywhere in
the list: Hyprland resolves bindings against the leading entry, so
"il,us" needed the fix just as much as "il" did.

Choosing a non-Latin layout (e.g. ara, il, ru) via /etc/vconsole.conf
leaves Hyprland unable to match Omarchy's Latin-keysym bindings, since
Hyprland resolves bindings against the first layout in kb_layout only.
Prepending 'us' when the detected layout doesn't already include it
keeps shortcuts reachable, and activating grp:alts_toggle lets the user
switch to their layout with Left Alt + Right Alt.
Adds shift:both_capslock alongside compose:caps so pressing both Shift
keys together toggles real Caps Lock. Caps Lock alone remains the
Compose key, and single-Shift behavior is unchanged. Provides an escape
hatch when Caps Lock gets stuck on (e.g. after an fcitx5 desync).
