The previous commit made the missing launcher honest; this gives Android a real one, so Login Flow v2 can complete on device. Builds `new Intent(ACTION_VIEW, Uri.parse(url))` and hands it to `startActivity` over JNI. The JavaVM and Activity come from ndk_context, which android-activity's glue populates at startup — the same handle Slint's backend uses, so there is no second VM to reconcile. The login worker is a plain std::thread and therefore unknown to the JVM, where any JNI call would abort the process. jni 0.22 scopes attachment to a closure rather than returning a guard, so the whole Intent is built and dispatched inside `attach_current_thread` and the thread detaches on the way out. Names use `jni_str!` and signatures `jni_sig!`, both compile-time: a typo is a build error rather than a NoSuchMethodError on the device. A pending Java exception is checked and cleared before returning, since leaving one pending makes the next JNI call fail somewhere unrelated; in practice it means ActivityNotFoundException, i.e. no browser installed. jni is pinned to 0.22 to match Slint's Android backend.

Building
Desktop:
cargo run -p darkroom-desktop
Android (containerised toolchain, see docker/android):
./docker/android/build.sh cargo ndk -t arm64-v8a build --release
Current state
Working: workspace, GPU context and compute pass, adaptive Slint shell, Android cross-compilation of the core crates.
Not yet working: the zero-copy display path. The build currently uploads frames through the CPU, which is exactly what ARCH §6.1 forbids — measured at 96% of frame time at 4K. Replacing it is spike S1, the project's highest priority.
cargo run -p dr-gpu --example bench --features readback
reproduces that measurement.
