- Fix bare excepts (replace with except Exception:) - Remove wildcard star imports from test step files - Add explicit imports for ConfigurationError, AgentCreationError - Add 'from err' to raise statements in except blocks - Fix loop variable binding with default arguments (B023) - Organize imports, fix trailing whitespace and blank line whitespace - Bump Python to 3.13 and update tool configurations
