Native screens can hide the tab bar and disable the iOS interactive back gesture through Craft, but the public NativeNavigationOptions interface rejects those options. Add the supported boolean fields so a sign-in screen can hide its chrome and offer an explicit return to public browsing with the normal typed API.
Type-checking regressions accept true and false, reject string values, and both platform bridges preserve hide/restore options and explicit navigation unchanged. The normal release preflight, focused tests, type check, lint (zero errors), and format check pass.
