Subject: [PATCH] fix(apps): bootstrap empty repos before the Git Data push
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

GitHub's Git Data API (blobs/trees/commits) returns 409 'Git Repository is
empty' on a repo with no commits — it cannot create the first commit. Ensure
main exists via a Contents API bootstrap commit (the generated README), then
chain the publish commit onto it.
