v0.4.10

Fixed

• gate_base no longer diffs against a stale local trunk branch. The
  trunk-candidate lookup tried bare local main/master before the
  remote-qualified origin/main/origin/master. A local trunk branch left
  un-checked-out since clone never advances even as origin/<trunk> moves
  forward on fetch, but it is still an ancestor of HEAD — so merge-base
  against it "succeeded" anyway, landing on a much older commit and dragging
  everything a teammate pushed since into keel gate g2's blast-radius and
  line-budget diffs. Remote-qualified names are now tried first.
