T1 Touch Bar on Linux without reinstalling macOS

This document describes the Linux-only method that successfully activated the firmware Touch Bar on a 2016 MacBook Pro with Apple's T1/iBridge coprocessor.

It covers two very different situations:

1. The T1 already boots as USB device 05ac:8600. Only the Linux driver is needed.
2. The T1 is stuck in recovery as 05ac:1281, or its EFI EmbeddedOS files are missing. The T1 must be personalized, provisioned, and booted before the driver can work.

Do not run the recovery workflow when the driver-only path is sufficient.
