- Introduced `test_echo_thin_waist.py` to validate the echo example's output for Thin Waist lines. - Added `test_address_validation.py` to cover functions for available interfaces, optimal binding addresses, and wildcard address expansion. - Included parameterized tests and environment checks for IPv6 support.
