v0.1.6

Graph labels

Fewer, clearer branch labels. A branch's local and remote refs now share
one label per name, marked with a local (branch) and/or remote (cloud) icon
instead of the origin/ text.
HEAD is folded into the current branch. The separate HEAD badge is gone;
the current branch is shown as a solid, bold chip in its own graph color. The
in-graph node highlight for the current branch is unchanged.
Labels are a touch larger for legibility.

macOS builds are ad-hoc signed (open with right-click → Open); pick the arm64 or
Intel installer for your Mac.
