Subject: [PATCH] fix(deploy): say which branches exist instead of failing
 inside git
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The installer clones BRANCH, which defaults to main — and the repository has
no main. Git's own "Remote branch not found" reads like a bad token or an
unreachable server, and the branch is the one thing here that is routinely
wrong. It now asks first and, when the branch is missing, prints the ones that
do exist and how to pass one.
