Three changes to the walk trail:
- Each name now carries its node's own key-derived hue (ours the white
you-style, a nameless node muted), the focus bold — instead of a flat
muted/bold trail.
- Walking to a node already on the trail truncates the stack to that
node's first appearance, dropping the loop we walked to get back there
rather than recording the round trip (this also subsumes the old
step-back-through-the-west-node special case).
- When the trail outgrows the line the head is dropped behind a leading
"…" rather than the tail being cut, so the focus and the steps that led
to it stay visible.
