Some compositors, niri among them, send the XKB keymap without a
trailing null, which the protocol allows; Raven treated that as an input
failure and gave up on the desktop before the first window. The keymap
is now taken whole when it has no terminator. A key the layout gives no
symbol (an unassigned or vendor key) passes with no virtual key instead
of ending the process, and one that gives several is known by the first.

AI-Scope: Diagnosed the "unsupported native input event" failure on niri
from WAYLAND_DEBUG output and a small wayland-client probe, and wrote
both changes and the keyboard_test case. Prompt: get an MSI installer
and the program it installs running under Raven on niri.
