## Summary

When `/etc/vconsole.conf` lists more than one layout and the first is non-Latin (e.g. `XKBLAYOUT="ru,us"`), Omarchy's Hyprland `kb_layout` becomes `us,ru,us` instead of `us,ru`. The duplicate `us` makes `grp:alts_toggle` (Left Alt + Right Alt) appear to work only **every other press**: the cycle `us -> ru -> us -> us` has no visible change on the last step.

## Steps to reproduce

1. Configure two layouts with a non-Latin first, e.g.:
   ```
   XKBLAYOUT=ru,us
   ```
   (as set by `localectl set-x11-keymap ru,us`)
2. Log into Hyprland.
3. Inspect the keyboard layout:
   ```
   hyprctl devices | grep rules
   ```
   Output shows: `l "us,ru,us", ... o "...,grp:alts_toggle"`
4. Press Left Alt + Right Alt repeatedly. The layout changes only every other press (RU -> US -> [no visible change] -> RU).

## Expected

`us,ru` — exactly one US and one RU, so every Left Alt + Right Alt press visibly toggles.

## Cause

`/usr/share/omarchy/default/hypr/input.lua`

```lua
local kb_layout = vconsole.XKBLAYOUT or "us"   -- line 31: "ru,us"

if non_latin_layouts:find(" " .. kb_layout:match("^[^,]*") .. " ", 1, true) then
  kb_layout = "us," .. kb_layout               -- line 44: "us," .. "ru,us" == "us,ru,us"
  kb_options = kb_options .. ",grp:alts_toggle"
end
```

Line 43 tests only the *first* layout (`"ru"`), but line 44 prepends `us,` to the *entire* layout list, producing `us,ru,us`. The duplicate is what breaks the perceived toggle.

## Suggested fix

Build the list explicitly instead of string-prepending, so `us` is placed first and never duplicated:

```lua
if non_latin_layouts:find(" " .. kb_layout:match("^[^,]*") .. " ", 1, true) then
  -- Move US to the front, keeping the original layout(s) and removing duplicates.
  local rest = {}
  for layout in kb_layout:gmatch("[^,]+") do
    if layout ~= "us" then rest[#rest + 1] = layout end
  end
  kb_layout = "us" .. (#rest > 0 and ("," .. table.concat(rest, ",")) or "")
  kb_options = kb_options .. ",grp:alts_toggle"
end
```

For `ru,us` this yields `us,ru` (not `us,ru,us`). Maintainers should adapt to match their style; the essential requirement is that a multi-layout vconsole value is handled without duplication.

## Workaround

Override in `~/.config/hypr/input.lua`:

```lua
hl.config({
  input = {
    kb_layout = "us,ru",
    kb_options = "compose:caps,shift:both_capslock_cancel,grp:alts_toggle",
  },
})
```
