Tauri's AppImage bundles the build host's graphics/display stack
(libEGL/libGL/libdrm/libgbm/libwayland-* + Mesa dri drivers) into usr/lib.
On many end-user systems (Arch/CachyOS, NVIDIA, Wayland) those clash with
the running kernel driver + Mesa and abort with EGL_BAD_PARAMETER -> a black
window (issue 2021). They load before any renderer choice, so the runtime
env fallbacks can't rescue it; per the AppImage excludelist they must come
from the host.
Add a CI-only post-build step (desktop/packaging/appimage/debundle-graphics.sh)
that extracts the built AppImage, strips exactly that graphics/display subset
(keeping webkit/gtk bundled for portability), and repackages in place so the
app falls through to the system's graphics libs. Wired into desktop.yml
between the Tauri build and the artifact upload.
Task 2023. Makes the AppImage the zero-install taste-test vehicle.

Native-first fix for the AppImage black window: a PKGBUILD that builds from source,
linked against SYSTEM graphics libs, so it renders on the host driver.
- desktop/packaging/arch/{PKGBUILD,thoughtsync.desktop,README.md}: `makepkg -si`
installs /usr/bin/thoughtsync + .desktop + icon; deps webkit2gtk-4.1/gtk3/...;
builds the frontend + `cargo build --release` (no tauri-cli). Uses the host
graphics stack -> avoids EGL_BAD_PARAMETER.
- Commit the icon set (desktop/src-tauri/icons/*.png, un-gitignored) so BOTH
`cargo build` (pacman) and `cargo tauri build` (deb/appimage) work without a
generate step; bundle.icon -> the 4 committed PNGs; drop the `cargo tauri icon`
step from desktop.yml.
- Broaden the WebKit software-render hardening (lib.rs) to ALL Linux (was
AppImage-scoped) so the native build also renders if system WebKit is finicky.
Can't CI-test the PKGBUILD (Arch-only; CI is Debian) -- operator builds locally.
desktop.yml re-verifies the deb+AppImage build with the committed icons.
