Ship the SteamVR driver and layer in the VR pack and let Setup uninstall it

The tracking pack becomes the vr pack: it now also carries the droiddeck-vr
driver and Vulkan layer, the Luma Ultra base calibration and the licenses of
everything inside it, so none of it ships in the APK. The guest copy is staged
from the pack before each session and removed when the pack is absent, which
also cleans up what older builds installed. Setup shows the VR module with
download and uninstall, the session drawer and Play SteamVR download it on
demand, and an older tracking or vr pack is replaced on upgrade.

 ## Requirements and install
 
-Use Android 9 or newer on a supported Adreno device (730 or newer, or 8xx). Adreno 6xx is experimental: DirectX 11 uses DXVK 2 and may run, and DirectX 12 games can still crash. Mali, Xclipse, PowerVR, and Adreno 710 are unsupported. No root is required. Allow about 3 GB for the runtime and 1.1 GB more for the desktop and emulators. Install the APK from [Releases](https://github.com/Droid-Deck/DroidDeck/releases), install the Linux runtime, then press **Play** and sign in. Steam downloads on first launch. Install **Desktop & apps** to use the desktop and emulators. The **Store** installs Linux apps and games from Flathub (ARM64 builds) with Flatpak; with additional options to install Appimages and set up scripts. **Stores** (Setup › Stores › "Show Stores in the rail") signs in to GOG, Epic Games and Amazon Games and downloads games into the Games storage. Epic keeps its direct API install path. Opening Epic Stores prepares Epic’s official Linux launcher preview. When installed, Epic games launched from DroidDeck use that client, and games installed in the client are imported into DroidDeck’s library and shortcuts. The x86-64 client runs through FEX on ARM and DroidDeck retains its Proton hooks; this preview and ARM setup are outside Epic’s listed Linux support. The cog on a store’s chip row sets its opening tab and download speed tier.

 On Android 14 and newer, before Steam launches, you must turn on **Disable child process restrictions** in Developer options. If this option is not available in developer settings (Android 12 and 13 devices), first launch of Steam will present a "Fix it for me" button, which will help automate the setup process.

+Luma Ultra now includes a shared starting calibration exported from the user's verified Fold7 profile on 2026-10-16. The VR pack's `luma-ultra-640x480.json` (`tools/packs/vr`) contains the original lens, stereo, and camera-to-head geometry without the source glasses' serial identifier. It applies only to the SDK-confirmed Luma Ultra primary `left0/right0` pair at 640 by 480. Matching saved device calibration takes precedence, including an unfinished personal fit that still requires distance validation. Missing, corrupt, or foreign profiles fall back to the model base; unknown serials can also use the base.
 
 The base enables experimental hand tracking without requiring every user to repeat board collection. It is not marked individually verified on other units. Tracking and setup show **Shared Luma Ultra calibration** while it is in use; diagnostics distinguish `calibrationSource` (`luma-ultra-base`, `device`, or `none`) from `calibrationVerified`. The existing `calibrated` availability field is true for either the base or a verified personal profile. The following board steps are optional refinement for a new device using the base; a newly calculated personal profile still needs the unchanged distance check before use. A successful distance check saves the profile for the connected identified glasses. Source validation does not establish manufacturing consistency or aiming accuracy across other units.
 
 Use the existing optional `droiddeck.vitureSdk` local property with the external VITURE Android SDK 2.4.0. No vendor headers or libraries are checked into the repository. `-PvitureSdkDir=` explicitly builds without the SDK. The ordinary runtime freshness checks remain enabled. Rebuild the ARM64 VR components with `tools/vr/build_windows.py`; its manifest includes `spatialpose_shm.h`.

CPU inference, the full model, concurrent camera inference, scheduled hand discovery, and automatic input-rate adjustment are the defaults, including after app restarts, reconnects, and provider restarts. **Show diagnostics → GPU hand inference** temporarily enables GPU until the next tracking restart; GPU remains experimental because SteamVR restarts and Vulkan device loss were observed during testing. Diagnostics report the selection as `handGpuEnabled` and the initialized detectors as `handInferenceBackend`; `not initialized` means detector startup has not completed. Sustained performance acceptance remains unresolved.
+The hand pipeline pins MediaPipe Tasks Vision 1.0.0, OpenCV 4.13.0, and the model and SHA-256 recorded in `tools/packs/vr/hand_landmarker.provenance.json`. The model, OpenCV and MediaPipe native libraries are downloaded on first use as part of the VR pack (`tools/packs`); the pack build and the inference worker verify the model checksum.

Diagnostics report the selection as `handGpuEnabled` and the initialized detectors as `handInferenceBackend`; `not initialized` means detector startup has not completed. Sustained performance acceptance remains unresolved.
 
 Hand input starts by copying 500 permille of stereo callbacks, approximately 12.5 pairs per second at the SDK's documented 25 Hz camera rate. On CPU, automatic adjustment can raise this to 600 or 800 permille (about 15 or 20 Hz) only after eight consecutive valid observations have sufficient processing and freshness headroom. Promotion requires average processing at most 55 ms and observation age at most 110 ms for 15 Hz, then at most 40 ms and 90 ms for 20 Hz. A moving average allows occasional scheduled discovery frames while preserving a sustained processing budget. An average above the selected period reduces the rate; any single processing cost of 80 ms or observation age of 140 ms immediately returns it to 500 permille. Tracking failure and detector resets also return it to 500. This policy requests more input only when processing can accommodate it; it does not guarantee that many completed or valid hand updates.
