Shiny.Maui.ContactStore — Device Contact Access That Does It All

MAUI Essentials handles contact picking well, but many apps need more — bulk queries, creating contacts, syncing from a backend, or searching across thousands of entries. Shiny.Maui.ContactStore fills that gap with full CRUD operations, a custom LINQ query provider that translates expressions to native queries, and a comprehensive contact model that covers everything both platforms support.
