Creating a wire with a direct pin-to-pin click (no user waypoints) now
routes around other components' bounding boxes instead of crossing
them. Routing happens exactly once, at creation: the routed corners are
stored as ordinary waypoints, so every later manual edit stays where
the user puts it — never re-routed.
Router (utils/wireAutoRoute.ts):
- tries the preview elbow first (clear -> keep existing behavior and
the WYSIWYG shape), then the opposite elbow, then A* over the
compressed grid spanned by pin coordinates and obstacle edges
inflated by an 8 px clearance, with a 40 px per-bend penalty so
straighter routes win
- obstacles are component boxes only (never boards — pins sit on both
board edges and detouring around a board produces absurd routes),
excluding the wire's own endpoint components, measured from the
rendered DOM; rects containing an endpoint are dropped
- any failure (walled-off target, oversized grid, no DOM) falls back
to the previous direct-elbow behavior
