Symmetric Diamond Odd Slot Entry

Gallery / Fan-out and Fan-in

A reconverging 2-way diamond under `diamond_style: symmetric` whose branches sit an odd number of grid slots apart, so the fork midpoint lands off-grid. The LR entry port centres on that midpoint -- matching the join station the branches reconverge at -- so the entry fork reads as symmetric as the exit fork (#1459).
