merge(feat/besadii): Integrate besadii at //ops/besadii r/569

This tool supersedes the previous //ops/sync-gcsr, which no longer
exists.

Besadii runs as a git post-receive hook and triggers builds for the
depot on sourcehut. Builds are only triggered for branches, not for
tags.

The sourcehut token is read from /etc/secrets where it has been
manually placed on camden.

Besadii was a hutt kajidic, and also part of the Hutt Clan.
