chore: fix trivial SonarQube code smells (S1905, S1118)

Remove three unnecessary (T[]) casts in CollectionPredicates.Default
(java:S1905, lines 88/98/108) — the varargs parameters are already typed
as T[] so the cast is redundant.

Add private constructor to Throws utility class and change abstract to
final (java:S1118, line 3) — prevents implicit public constructor and
accidental subclassing while keeping the static API intact.
