com.unity.xr.hands 1.1.0 Package Notes

Added `isTracked` to `XRHand`.
Added `trackingAcquired` and `trackingLost` to `XRHandSubsystem`.
Added `XRHandDevice` and automatic managing of it if the Input System is enabled and hand-tracking is enabled in the target platform's build settings.
The `HandVisualizer` sample now opts into using optimized controls in the Input System if you enable the **Use Optimized Controls** option. You must be on at least version 1.5.0 of the Input System package for this to have an effect.
Added `handedness` getter property to `XRHandJoint`.
Added `updateSuccessFlags` property to `XRHandSubsystem` to allow the most recent `UpdateSuccessFlags` to be polled. This value matches the argument to the `updatedHands` callback.
The OpenXR package must be installed and enabled for these to work:
Added OpenXR support through `HandTracking` and `OpenXRHandProvider` types.
Added support for Meta Hand Tracking Aim extension in OpenXR through `MetaHandTrackingAim`.

`MetaAimHand` and `MetaAimFlags` have been moved outside of the `MetaHandTrackingAim` type and moved from the `UnityEngine.XR.Hands.OpenXR` namespace to `UnityEngine.XR.Hands`. The same input bindings will work the same as before.
The HandVisualizer sample meshes has been updated.
Changed Hand Visualizer component so it skips setting the shared material on the instantiated hand mesh prefabs when the Hand Mesh Material property is not set.
Providers must now create joints with a known `Handedness` during `TryUpdateHands` when calling `XRHandProviderUtility.CreateJoint`.
Changed Meta Aim Hand input devices that are added to the Input System to continue updating the `devicePosition` and `deviceRotation` controls even when the `MetaAimFlags.Valid` bit flag is not set. Instead it uses whether the hand root is valid. In practice, the `MetaAimFlags.Valid` flag currently does not necessarily indicate whether the pose is valid but instead is based on whether the user is in a natural orientation for distant UI panel selection.
Changed HandVisualizer sample by adding an Assembly Definition file (`.asmdef`).

Fixed issue where OpenXR would incorrectly report joints as having updated when they weren't actually tracked that frame. `XRHandSubsystem`'s `trackingAcquired` and `trackingLost`, as well as `XRHand.isTracked`, will now work as expected.
Fixed issue where `/isTracked` and `/trackingState` controls would never clear.
Fixed `XRHandDevice` and `MetaAimHand` to also include `InputDeviceCharacteristics.TrackedDevice` in the `XRDeviceDescriptor`.
Fixed lifetime of GameObjects in `HandVisualizer` sample.
Fixed `HandVisualizer` so it uses the `XROrigin.Origin` property instead of the Transform of the `XROrigin` itself when transforming joints.
Reinstated the validation rule that the Meta Touch Interaction Profile is required in the OpenXR Interaction Profiles list.
OpenXR hand root poses now match the wrist, not the palm.
