## Summary

`omarchy-launch-or-focus` matches its pattern against the window **title** as well as the class. For the `focus = true` web app bindings, the pattern is the binding's description ("WhatsApp", "Google Maps", "Google Photos", "Google Messages"). So any ordinary browser window whose active tab title contains that word is taken as the web app. The binding then focuses the browser window and never launches the web app.

## Steps to reproduce

1. Make sure the WhatsApp web app is **not** running.
2. In the browser, open a normal tab on https://www.whatsapp.com/ (title: "WhatsApp | Secure and Reliable Free Private Messaging and Calling"), or on any WhatsApp group invite page (`chat.whatsapp.com/…`, title "WhatsApp Group Invite"), and leave it as the **active tab** of that window. The window title follows the active tab, so a background tab doesn't trigger it.
3. Press `SUPER + SHIFT + ALT + G`.

**Expected:** the WhatsApp web app launches.
**Actual:** the browser window with that tab gets focus, and the web app never launches. (Reproduced on the system below.)

The same happens with `SUPER + SHIFT + S` (Google Maps) and `SUPER + SHIFT + P` (Google Photos) whenever a browser window's active tab is on maps.google.com or photos.google.com, since those tab titles contain "Google Maps" and "Google Photos". If the web app is already open, the result depends on the order in `hyprctl clients`, so the binding can still focus the browser tab instead of the web app.

## Cause

`bin/omarchy-launch-or-focus`:

```bash
WINDOW_ADDRESS=$(hyprctl clients -j | jq -r --arg p "$WINDOW_PATTERN" '.[]|select((.class|test("\\b" + $p + "\\b";"i")) or (.title|test("\\b" + $p + "\\b";"i")))|.address' | head -n1)
```

`default/hypr/helpers.lua` → `o.launch_webapp_sole(name, url)` passes the binding **description** as the pattern:

```lua
return "omarchy-launch-or-focus-webapp " .. shell_quote(name) .. " " .. shell_quote(url)
```

Replaying that jq filter over a client list with `{"class":"chromium","title":"WhatsApp | Secure and Reliable … - Chromium"}` selects that browser window for the pattern `WhatsApp`, and `Google Maps - Chromium` for `Google Maps`.

## Suggested fix

For web apps, match on the window **class** only, derived from the URL rather than the description. Chromium-based `--app=` windows get a class like `chrome-web.whatsapp.com__-Default` (`brave-…` on Brave), so `omarchy-launch-or-focus-webapp` could build the pattern from the URL's host (e.g. `^[a-z-]+-web\.whatsapp\.com_`) and check it against `.class` only. Non-web-app callers of `omarchy-launch-or-focus` can keep the current behaviour.

## System

- Omarchy 4.0.4-1
- Hyprland v0.56.2
- Browser: Chromium (default)
- `bin/omarchy-launch-or-focus` and the WhatsApp binding are unchanged on current `master`.
