Key features and bugs addressed

1. Feature

   Added

2. Feature

   Added `Uninitialize` to the `VivoxService` , allowing users to fully uninitialize the SDK and re-initialize it later.

3. Feature

   Added visionOS as a standard supported platform. visionOS native libraries are now included directly in the `com.unity.services.vivox` package and no longer require the separate `com.unity.services.vivox-visionos` package.

4. Feature

   Added support for Linux as a platform. Only x86_64 architecture is supported.

5. Fix

   Fixed

6. Fix

   Fixed a `KeyNotFoundException` that could be logged when leaving a channel or logging out while a channel was still disconnecting.

7. Fix

   Fixed device operations (muting/unmuting devices, adjusting device volume, and setting the active device) logging a `VivoxApiException` after logout because they were still addressing the account that had signed out.

8. Fix

   Fixed channels not being fully cleaned up on logout, which left stale internal event subscriptions that could cause duplicated channel events after logging back in and rejoining the same channel.

9. Fix

   Fixed a WebGL issue where channel resources were not fully released when logging out while still connected to a channel, which could gradually increase memory usage across repeated login and logout cycles.
