Revert the To<T> array swap; keep params IEnumerable + priority

The Phase 4 change of To<T>'s params overload from IEnumerable to a
(Field,Column)[] array gave no functional benefit: params IEnumerable<(...)>
accepts the identical call shapes (multi-arg new(...), collection expressions,
tuples), verified empirically. The array was only ever REQUIRED for the Results
family, whose same-arity IEnumerable sibling caused a CS0111 collision -- To<T>'s
sibling has an extra `bool clearSourceTable`, so no collision, so IEnumerable is
fine and is the more flexible (a List binds the params overload directly).

The real enabler was the [OverloadResolutionPriority(1)] added alongside, which
disambiguates the collection-expression forms; that stays. Only the array->
IEnumerable swap is reverted. PublicAPI baseline updated.

Build 0/0; 102 tests (To<T> assumption tests now bind through params IEnumerable).
