context-signals hardcoded ['main', 'master'] as diff-base candidates, so
repos integrating through develop (or any other branch) diffed against
the wrong base: git.changedFiles carried the entire divergence and
downstream commands scanned the wrong set (issue #302).
The base is now detected, most specific signal first: the branch's
configured upstream (@{u}; a branch pushed with -u tracks itself and is
skipped by the self-check), then the remote's default-branch symref
(origin/HEAD), then the conventional integration names including
develop. The conventional fallbacks are withheld when the current branch
is itself one of them, so sitting on main in a repo that also has
develop keeps the working-tree scope instead of diffing two integration
branches against each other.
Five tests (three failing-first): develop-based feature branch,
origin/HEAD detection with a non-standard default name, upstream
tracking, on-the-integration-branch fallback, and the
integration-vs-integration guard.
