Drop the debs/ subdir and put every download at the repo root so both the
Debian .deb and the Windows .msi/.zip show up directly in the file list.
Stop gitignoring the binaries; add a root SHA256SUMS covering all of them.

Binaries only, no source. Windows .exe/.msi go up as release attachments
(they are 64-77 MB each, too big for git history); .deb packages are
committed under debs/ like the other *-deb repos.
