Desktop-mode (KWin) streaming had no input: the path was libei via the
RemoteDesktop portal, which (a) isn't reachable from the host service env
and (b) requires a human to approve "Allow remote control?" — a
non-starter on a headless box. KWin's own headless RDP server (krdpserver)
solves this with org_kde_kwin_fake_input, authorized by the exact same
.desktop X-KDE-Wayland-Interfaces grant we already ship
(org_kde_kwin_fake_input is listed alongside zkde_screencast_unstable_v1).
Add a fake_input injector: vendor the protocol XML, bind the global as an
ordinary Wayland client, authenticate (auto-accepted for an
interface-authorized client — no dialog), and translate pointer (rel/abs),
button, scroll, keyboard (raw evdev keycodes resolved by KWin's own keymap)
and touch. Select it for KWin (compositor=="kwin" or XDG_CURRENT_DESKTOP
KDE); GNOME stays on libei (it has neither fake_input nor the wlr
protocols). PUNKTFUNK_INPUT_BACKEND=kwin forces it.
cargo check + clippy + fmt green.
