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).
