Forgejo now allows only squash and fast-forward-only, so the three method= calls
in this file named styles the API rejects: rebase for feat->dev, and merge
commits for both promotions. An orchestrator following them gets a 405.
The fast-forward paragraph said adopting ff-only 'needs a one-time
reconciliation of the protected branches, which is the owner's decision'. That
decision was taken and the reconciliation done — the trees were already
identical, so it carried no content. release subset-of main subset-of dev now
holds and promotions land the branches on the same SHA. The paragraph keeps the
structural explanation, since it is what makes the failure mode recognisable,
and now points at reconciliation as the remedy.
