fix: align the left home cards with the shortcut tiles

 - The HOME role must be granted for the dashboard to replace the tablet home screen. On the emulator use `cmd role add-role-holder`; the Settings row uses `RoleManager`.
 - There is no Home-role banner. The one-time first-run tip uses `LauncherController.homeRoleHintShown`; do not show it again.
 - The long-press hint uses `onboarding.firstLaunchAt` and `HomeHint`: it is visible only for the first ten minutes after a fresh installation. Upgraded installs are migrated to an expired window and never see it again.

+- Screen-space is deliberately finite: test the 16-button grid at 1280×800, 1280×720 and 1024×600. The shortcut grid is bottom-anchored so a short row sits on the bottom edge; keep that behavior when changing layouts. The left card stack is inset by `ShortcutGrid.labelAllowanceFor(compact)` so its bottom aligns with the shortcut tiles, above their labels. The grid includes All apps; Settings sits in `StatusCluster` and does not consume a slot. Avoid unbounded `ListView`s inside `Column`s.
 - `tool/emulator.sh` starts a headless AVD with the **host GPU**; SwiftShader segfaulted on this machine's API 35 image. Use `CARDASH_GPU=swiftshader_indirect` only as a fallback. Use `adb exec-out screencap -p` for screenshots; there may be multiple `adb` binaries on PATH, so use the absolute one.
 - While CarDash is foreground, `MainActivity` consumes hardware volume keys and adjusts `STREAM_MUSIC` so they match the dashboard, unless `AudioManager.isVolumeFixed` is true; on fixed-volume car units the keys pass through to the vehicle amplifier and the on-screen slider is disabled with an explanation. `SystemBridge.setVolume` falls back to relative `adjustStreamVolume` steps when a unit ignores absolute `setStreamVolume`, then to a `FLAG_SHOW_UI` write that may reach the vendor's own volume panel. Long-pressing **Media volume** toggles `SystemController.volumeDiagnostics`, which shows the raw `index/max`/`min`, fixed flag, control source, vendor state, all stream levels and the last write result; the native side logs the same data under `CarDashVolume`. Do not remove this path without providing another sync path; otherwise Android controls the ring stream when no media is playing.
 - FYT/Syu head units (Joying, Junsun, Teyes, Atoto and similar Chinese firmware) own the amplifier in the MCU, so the Android media stream is not what the driver hears. `SyuVolumeBridge` binds `com.syu.ms` (`app.ToolkitService`, action `com.syu.ms.toolkit`), fetches module 4 (`getRemoteModule`, transaction 1) and sends `cmd(0, [level])` for the absolute master volume (command 0 = `FinalSound.C_VOL`, range 0–36); it also subscribes to update 2 (level) and 3 (mute), so knob changes and slider changes stay in sync. `SystemBridge.readVolume` reports `source = syu` while that bridge is connected. This path is verified on a real Android 13 FYT/Syu unit: the on-screen slider and the car's own volume control agree. `MainActivity`'s hardware-key path is unchanged: the car's own knob and steering-wheel volume are handled by the MCU, not by injecting extra steps. No permission, root or manifest change is needed; if the package, service or module is missing the bridge stays disconnected and the `AudioManager` path is used. Never make the vendor bind a hard dependency, and never let a failed binder call crash the app.
