Cursor and Greptile converged on one root cause from the previous round:
candidate revs stopped at origin (develop tried only develop and
origin/develop; a remote-default entry carried only its own rev), so the
name-level dedup discarded a same-name base living on another remote. A
fork-parent layout with develop only as upstream/develop, or a pruned
origin/main beside a live upstream/main, lost its base entirely.
revsFor(name) now expands to the local branch plus <remote>/<name> for
every remote (origin first), and all named candidates use it, which is
exactly what makes the dedup safe. Two failing-first tests cover the
upstream-only develop and the pruned-origin/live-upstream main shapes.
