Every Qualcomm session started the driver through libhybris twice before
Steam: droiddeck-qualcomm-caps (up to 20 s) and glxinfo for the browser's
OpenGL level (up to 15 s). Both answers only change with the driver, so
they are now saved under $XDG_CACHE_HOME/droiddeck and reused while the
driver file (SHA-256), the selected driver, the bridge build, the layers
and the check script are unchanged. Gamescope's linux-dmabuf global is
still checked every session, failed or empty results are never saved, and
the log marks a reused result.
