Pull request overview

This PR adds three helper functions (First(), Second(), and Third()) to the bdd package that extract individual values from multi-value return functions. These utilities are particularly useful in test assertions where you want to test a specific return value from a function that returns multiple values.

Changes:

• Added First(), Second(), and Third() helper functions using generics and variadic parameters to handle multi-value returns
• Added comprehensive BDD-style tests for all three functions
