M4 Android stage 1 (input). Kotlin captures input and forwards it over JNI to
NativeClient::send_input (the connector is linked as a Rust crate).
- crates/punktfunk-android: 4 JNI send fns (pointer move / button / scroll / key)
building InputEvent with the GameStream wire codes — ungated, &self on the Sync
connector (safe from the UI thread).
- clients/android: Keymap.kt (Android KEYCODE_* -> Windows VK, the host's wire
contract, mirroring the Linux/Apple tables); Activity-level dispatchKeyEvent forwards
hardware keys to the active session (above the Compose focus system, so it's reliable);
a Compose touch-trackpad overlay -- 1-finger drag -> relative move, tap -> left click,
2-finger drag -> scroll.
Verified live (emulator -> gamescope host on the LAN box, synthetic `adb input`): host
received 31 input datagrams (input=31) and libei injected KeyDown/KeyUp, MouseButtonDown/Up
and MouseMove all emitted=true. Physical-mouse pointer capture + gamepad are next.
