UrdaVarg Roadworks 0.14.1 road-start hotfix
--------------------------------------------------
- Uses registered Road Node identity when validating A/B.
- Preserves normal per-step UE consumption when the Energy bridge is available.
- If the private Energy bridge fails to resolve, construction falls back to the
  already verified powered-node gate instead of silently stalling.
- Road and bore geometry, materials, pipes, planner behavior and dimensions are unchanged.
