Extend the Assertion Set
CHALLENGE
Difficulty: intermediate+25 XP
Two assertions every framework needs: Throws<T> (true iff the action throws exactly T or a subclass — other exception types must propagate as a false-ish *result*, not escape) and SeqEq<T> (value equality over two sequences, including null handling).
``csharp
static bool Throws<T>(Action a) where T : Exception;
static bool SeqEq<T>(IEnumerable<T>? a, IEnumerable<T>? b); // null == null → true; one null → false
