Move maintainer tooling out of the repo

Git hooks, the upstream sweep and the SBo delivery workflow are the
maintainer's operational tools, not package knowledge. They now live in a
private workspace that wraps all three SlackBuild repos, with one shared
copy of each hook instead of three drifting ones.

Also in this pass:
- AGENTS.md: checksum loop documented as sbodl (sbofixinfo does not fix
  checksums), nvchecker must not run without a token config, prefer
  use_latest_release over use_max_tag
- README: Git Hooks section replaced by a short Contributing note
- sweep report renamed to LAST_SWEEP.md across all three repos

-# 20220315 bkw: SBo pre-commit hook, wrapper for sbolint.
-
-# Installation:
-
-# Copy this to <gitdir>/.git/hooks, mode 0755 (or anyway, make it
-# executable). Also get sbolint and install it somewhere on $PATH,
-# like /usr/local/bin. sbolint comes from:
-
-# https://slackware.uk/~urchlay/repos/sbostuff/plain/sbolint
-
-# That's a wgettable URL. You can also clone the sbostuff
-# repo from https://slackware.uk/~urchlay/repos/sbostuff if you want.
-
-# Usage:
-
-# Just do your usual "git commit". When you do, sbolint will run on
-# the build you're updating. If it finds any issues, it will cause the
-# commit to abort, so you can fix whatever's wrong and try the commit
-# again.
-
-# Since sbolint isn't perfect, you can skip the check for any commit
-# by running e.g:
-
-#  SBOLINT=no git commit <arguments>
-
-# You can also run sbolint by itself, and read its documentation with
-# "sbolint --docs".
