Re: Re: request for review: Debian packaging docs for coding agents

Thanks Andrey. Updated both docs.

Now they require "sbuild" or a clean chroot build. The "gbp" section now
shows "git-buildpackage" commands.

I also fixed the Python dependency wording. Build-time test imports go in
`Build-Depends`.

In my experience modern LLMs manage to build a package that will install,
on my system at least, often with a oneshot... but usually the package
source ends up filled with a lot of strange mistakes. I try to feed
explicit, succinct yet complete docs into context wherever possible.
