v1.2.0

Added

• Array.Values — iterator over all values (iter.Seq[*T]), completing the Keys / Values / All trio

Changed

• Array.Iter renamed to Array.Keys — aligns with Go 1.23 iterator conventions (iter.Seq[K] iterators are named Keys)
• Array.Iter2 renamed to Array.All — aligns with Go 1.23 iterator conventions (iter.Seq2[K, V] iterators are named All)
• IterConfig renamed to IterOptions
