A linked worktree whose base predates (or carries) wrapper changes relative
to origin/main previously hit a hard refusal, even though the canonical
checkout held exactly the trusted origin/main wrapper the refusal message
told the operator to go run by hand. When the canonical checkout is clean
and byte-identical to fetched refs/remotes/origin/main, exec it with a loud
stderr notice instead; advisory dev-wrapper opt-in keeps precedence, and
the refusal remains when no anchor-matching wrapper exists on disk.
Also records the squash-merged stacked-branch rebase gotcha
(git rebase --onto origin/main <landed-branch>) in the PR maintainer skill.
