…ting scheduler for minimization workloads. This change introduces a `Scheduler` abstract base class, and refactors `ASAP`, `MinCut`, and `SDC` scheduling algorithms to implement this interface. A new `RandomScheduler` is also added. The `run_pipeline_schedule` utility is updated to use this new interface. Additionally, a new option and flag `--find_bounds_strategy` are added, allowing a different scheduler (defaulting to ASAP) to be used for finding minimum clock period and worst-case throughput bounds, which can be faster than using the main scheduling strategy. Error handling in `run_pipeline_schedule` is also improved. The 'random' scheduler is also updated to make use of the ASAP scheduler bounds to do a much better job at consistently choosing allowable schedules. PiperOrigin-RevId: 910927564
