## Summary Continue my changes to introduce the HAL infrastructure from https://github.com/crosspoint-reader/crosspoint-reader/pull/522 This PR touches quite a lot of files, but most of them are just name changing. It should not have any impacts to the end behavior. ## Additional Context My plan is to firstly add this small shim layer, which sounds useless at first, but then I'll implement an emulated driver which can be helpful for testing and for development. Currently, on my fork, I'm using a FS driver that allow "mounting" a local directory from my computer to the device, much like the `-v` mount option on docker. This allows me to quickly reset `.crosspoint` directory if anything goes wrong. I plan to upstream this feature when this PR get merged. --- ### AI Usage While CrossPoint doesn't have restrictions on AI tools in contributing, please be transparent about their usage as it helps set the right context for reviewers. Did you use AI tools to help write this code? NO
