Spec described the overlay as a single Graphics in the origin tile,
which was both the bug source and out of date after the F8-07 fix.
Updates the Open / Tick steps to describe the nine-copy replication
and the torus-shortest line endpoint contract.

Pick overlay (anchor ring, cursor line, hover outline) was drawn into a
single Pixi container — copies[ORIGIN_COPY_INDEX] — so any view of a wrap
copy lost it: picker from A1/A2 to the right (across the seam) showed no
hover highlight on A3's wrap copy, and the picker on A3 (x≈1.44, near the
left edge) put its anchor far left of the viewport. Fix replicates the
overlay across all nine torus copies (matching how primitives and fog
already render) and switches the cursor-line endpoint to torus-shortest
geometry via torusShortestDelta. Anchor and hover-outline coordinates
stay canonical; the per-copy replication renders them under the user's
view in whatever tile is on screen.
Also reduces cargo-route arrow strokes: COL/CAP/MAT 2->0.6 wu and EMP
1->0.4 wu (~3 / ~2 screen px at typical zoom) per the owner's request.
Tests cover the new torus path: source near the left edge with cursor on
the wrap copy across the seam (x axis), source near the top edge with
cursor across the y seam, and a guard that anchor / hover-outline coords
stay canonical regardless of the world argument.
