Walkthrough

Minor formatting changes in error message construction across two endpoint files. Both replace explicit str(e) casting with {e!s} format string conversion specifier in exception handling paths. No control flow or logic modifications.

Error Message Formatting src/app/endpoints/a2a.py, src/app/endpoints/health.py	Updated error message string formatting to use {e!s} conversion specifier instead of {str(e)} in exception interpolation for APIConnectionError and health check error paths.
