[release build] XOS-16.2 02/06/2026 for Pong

This is an official release of halogenOS.

Changelog:
This build fixes AVB signing. WARNING: Due to an error in the CI building logic, prior builds have had their images signed with the AOSP test key. This build switches to the real XOS keys. If you have a locked bootloader and experience boot failures, we recommend unlocking and re-locking the bootloader. That said, if you already have the custom key (the pkmd.bin) flashed, you should not have any issues. I, @xdevs23, apologize for any invonvenience this causes. I have implemented signature verification in the build process to catch these type of issues in the future. Note: this will likely trip your bootloader's verified boot check and cause the state to change to yellow. This is the expected behavior. If you want to use your own keys, feel free to re-sign the images yourself.
