master b0d348c921 Add Y-axis gutter expansion for routing-aware node placement ...

The Y-axis counterpart to ExpandVerticalCorridorGutters: after edges
are routed, detects horizontal segments with under-node or alongside
violations, then inserts horizontal gutters by shifting all nodes
below the violation point downward. Re-routes with expanded corridors.

This is the architectural fix for the placement-routing disconnect:
instead of patching edge paths after routing (corridor reroute,
push-down, spread), the gutter expansion creates adequate routing
corridors in the node placement so edges route cleanly.

Runs after X-gutters and before compact passes, up to 2 iterations.
