Since Windows defaults to DirectX 12 only (#50), PCs whose graphics chip has
no DirectX 12 driver (Intel 4th generation on Windows 11) fall back to WARP,
Microsoft's software renderer, and the app lags. Before eframe creates its
instance, WordCraft now probes DirectX 12 with a short-lived instance: a
hardware adapter that meets eframe's device limits keeps DirectX 12 only;
WARP only enables OpenGL next to DirectX 12 (GPU preferred, WARP as last
resort); no adapter, or only GPUs below the limits, uses OpenGL alone.
WGPU_BACKEND still overrides everything. The choice is logged, and the
decision is a pure function with unit tests.

On desktop, the Print button on File › Print now renders the document
to PDF, writes it to a fresh wordcraft-print-*.pdf in the OS temp
folder and opens it without blocking the window: in Preview on macOS,
and in the default PDF app on Linux/BSD (xdg-open, gio, ...) and
Windows (via the `open` crate, already in the tree). The user prints
from there through the system print dialog. If no viewer can be
started, the status bar says so and the file is removed. Print files
older than an hour are cleaned up off the UI thread at start-up and
after each print.
