The bench APK aborted on Iris's phone in AndroidRenderer::new with only
a truncated "wgpu error: Validation Error". This build carries ai-app-2
commit 46246ea: a renderer-creation failure now reports the adapter,
its limits/downlevel flags, and wgpu's full error chain on screen and
in logcat instead of aborting, and build-apk.sh no longer forces the
GLES backend (force-gles was meant only for one emulator measurement,
but the delivered APK inherited it regardless of target -- the named
hypothesis for the crash, per ai-app-2's RUST.md P0 box).
