This doesn't solve the version db management. The issue with that is that we have to figure out when to use --overwrite-version. We could avoid this issue by comparing the version file with the one from the branch we want to merge into and only add the flag if they're not identical.

Correct, this doesn't solve anything with versioning and just adds a simple formatter. I mentioned it in the other discussion as a starting point for generic vcpkg helper pre-commit hooks.

How would you determine the base branch (merge target) on the developer machine where this hook is run?
