Blurred background on Wayland

Dupe Check

[X] I have searched Warp feature requests and there are no duplicates

Describe the solution you'd like?

The solution I'd like is pretty straightforward. Enable blurred background support on Wayland. I think it's not supported by X11 but it is on Wayland. Other popular apps do this on Linux.

Is your feature request related to a problem? Please describe.

Not really a problem.

Additional context

What an LLM told me:

To achieve a blurred background effect for a Linux desktop app on Wayland, you have a few approaches depending on your toolkit and compositor:

1. If using GTK4:

// Set window transparent
gtk_widget_set_opacity(window, 0.9);

// Enable blur using portal (if supported by compositor)
GtkWindow *window;
gtk_window_set_blur_background(window, TRUE);

2. If using Qt:
// Enable transparency
window->setAttribute(Qt::WA_TranslucentBackground);

// Set blur hint using KWindowEffects (KDE)
KWindowEffects::enableBlurBehind(window->winId(), true);

3. Using pure Wayland protocol:
You'll need to implement the `kde-blur` or `wlr-layer-shell` protocol. Here's a basic example:

// Request blur via compositor protocol
struct zwlr_layer_surface_v1 *surface;
zwlr_layer_surface_v1_set_blur(surface, true);

Note that blur support depends on your Wayland compositor:
- KDE Plasma (KWin) supports it well
- GNOME requires extensions
- Sway/wlroots-based compositors may have varying support

The most reliable approach is checking compositor capabilities at runtime and gracefully falling back when blur isn't supported.
