chore(sync): record main's ancestry on beta

main held 12 commit(s) beta did not. Merged with -s ours: beta's
tree is kept BYTE FOR BYTE and only the ancestry is recorded, so the
beta -> main promotion stops conflicting on files where beta is simply
newer.

Not brought over -- beta is hundreds of commits ahead of main, so these
are the OLDER copies, and several are dead Forgejo/Codeberg CI that
development deliberately removed:
