- Updated README.md to reflect changes in load testing commands and added usage examples for Bash scripts. - Converted PowerShell load testing scripts to Bash equivalents for better cross-platform compatibility. - Added new Bash scripts: run-loadtests.sh, summarize-artillery.sh, and summarize-k6.sh to mirror existing PowerShell functionality. - Updated admin-api.js and ws-chat.yml for consistency and improved performance metrics reporting. - Enhanced error handling and output formatting in summary scripts for better readability.
