Notes

Pull request overview

This PR addresses code quality issues by renaming imported symbols that shadow Python built-ins. The main changes involve aliasing ConnectionError and ConnectTimeout from the requests library, and aliasing exit from the sys module to avoid conflicts with built-in names.

• Renamed requests.ConnectionError to RequestsConnectionError and requests.ConnectTimeout to RequestsConnectTimeout
• Renamed sys.exit to sys_exit to avoid shadowing the built-in exit()
• Updated IDE configuration files to reference Python 3.14
