Optimize stroke cache and benchmark configurations

- Updated stroke cache to use parallel processing for pixel checks.
- Modified benchmark commands in notlar.txt to ensure consistent output and baseline comparisons.
- Created a plan for merging criterion directories and optimizing benchmark performance, including pre-allocation of buffers and various optimization strategies.
- Removed redundant output directory settings in benchmark files and ensured all benchmarks write to a single criterion directory.
- Updated documentation to reflect changes in benchmark paths and configurations.
