expo-contacts

native-seam: upstream expo-contacts JS runs from the bundle; the seam now seeds the standard Apple sample address book the bare reference iOS Simulator ships (Kate Bell, Daniel Higgins, John Appleseed, Anna Haro, Hank Zakroff, David Taylor — the long-stable *@mac.com sample set), so getContactsAsync/getContactByIdAsync return the same contacts a real RN app sees on the conformance Simulator instead of an empty list. add/update/remove then mutate that store like CNContactStore.
