Feature request

After restarting nav2 the robot should know it's last known position.

Feature description

I’m currently looking for a way to persist the last known pose of the robot so that, after restarting the Nav2 stack, the robot can be automatically localized again without having to set an initial pose manually. In our use case, we typically don’t move the robots by hand, so restoring the last pose would be very practical.

Implementation considerations

Even if AMCL crashes, it should be restarted automatically, and the robot should keep its position. Ideally, this involves writing to a file in a way that is resistant to corruption.

I would be interested in Implementing it myself once all the details are clear.
