Code Review
This pull request introduces dynamic scaling of the resistance-aware nets percentage throughout the routing process, defining initial, mid, and final percentage constants and updating the routing logic accordingly. The feedback highlights a critical issue where skipping the rerouting of nets with positive slack entirely during the main routing phase could severely impact routability and congestion resolution; it is recommended to disable resistance-aware routing for these nets instead of skipping them. Additionally, the newly introduced percentage constants should be defined as floats to maintain type consistency with the target variable and prevent implicit conversions.

Summary
Apply resistance-aware to critical nets in three phases:
Applying res-aware slowly reduces the number of nets pushed to upper metal layers without hurting QoR.
