The measurements behind the preceding commits needed a repeatable way to drive a real Android TV box and read both sides of the frame. `dumpsys gfxinfo` alone is not enough (it sees the HWUI composite, not Flutter's UI and raster threads), and DevTools is not scriptable. - `vmclient.mjs` -- Dart VM Service client over WebSocket, plus percentile and timeline helpers and a CPU self/total-time reducer over `getCpuSamples`. - `scenarios.mjs` -- repeatable D-pad workloads. Keys are sent as one batched `input keyevent` invocation per burst, because a separate invocation per key costs more on the device than the interaction being measured. - `bench.mjs` -- runs a scenario and correlates Flutter's own frame phases (`Animator::BeginFrame`, LAYOUT, SEMANTICS, BUILD, PAINT, `Rasterizer::DoDraw`) with HWUI framestats, reporting medians over repeats. - `profile.mjs` -- CPU self/total time by function plus an allocation profile. - `launch.sh` -- cold-launches the profile build, sets up its own port forward and prints a host-reachable VM Service URI. Passes `--ez enable-dart-profiling`, which only `flutter run` supplies by default, and wakes the display first because `am start -W` silently reports no `TotalTime` when the screen is off. Not referenced by `lib/` and not packaged; `tools/` is outside the APK.
