merge: back-merge main (v2.7.43) into dev

dev and main had diverged on the version line alone: dev sat at 2.7.41 while
main shipped 2.7.43 through two release commits that never came back. main was
not an ancestor of dev, so the next promotion would have been a merge rather
than a fast-forward, and the ledger would have kept drifting with every release.

merge-tree confirmed the merge is clean and that the whole material change is
one line of package.json. Promotion from here is a real fast-forward.
