Code Review

This pull request updates the OpenROAD subproject commit and adjusts the regression baselines (rules-base.json) for several designs, including swerv, tinyRocket, chameleon, and microwatt. The review feedback highlights significant performance degradations in the updated baselines: specifically, a 20% degradation in setup TNS for the swerv design and a substantial increase in antenna violating nets (from 1 to 4) for the microwatt design. Per repository guidelines, tracking issues should be created to address these degradations before or after merging.
