Code Review
This pull request updates the OpenROAD subproject commit and adjusts several baseline design rules and timing metrics in rules-base.json. Feedback highlights a significant degradation in the global routing setup TNS (globalroute__timing__setup__tns), suggesting a need to analyze the global routing stage for potential congestion or optimization issues rather than just updating the threshold.

The timing metric 'globalroute__timing__setup__tns' shows a significant degradation of approximately 37% (from -206.0 to -282.0). While other timing metrics like 'cts__timing__setup__ws' and 'finish__timing__setup__ws' have improved, this large degradation in global routing TNS suggests potential routing congestion or optimization issues introduced by the OpenROAD update. It is recommended to analyze the global routing stage to identify the cause of this regression rather than simply relaxing the regression threshold.
