Request for feedback: debcraft improve

Hi,

The command `debcraft improve` can be run in a Debian packaging git
repository to automatically fix several mechanical maintenance items
common for most Debian packages.

I recently refactored the code so that each check is in a separate
script and each fix results in a well-documented git commit.

If you are using Debcraft, I'd like to invite you to test the latest
version (0.9.1) and give feedback on how these automatic fixes work
for you and potentially contribute more at
https://salsa.debian.org/debian/debcraft/-/tree/main/src/container/improve.d

I am tring to do this in a way that it does not overlap too much with
lintian-brush. There are also cme and other fixer scripts, but I am
trying to achieve something simpler and more integrated.
