v1.0.0-beta

First beta - feature-complete and API-stable. All five ad formats + UMP consent + iOS ATT + the JavaScript API (Admob module + Web Component) + x-admob::banner Blade component + built-in test page + banner offset + auto safe-area inset + frequency caps + ADMOB_ENABLED kill-switch + ADMOB_DEBUG. 82 tests green. Android device-verified; iOS implemented but not yet hardware-tested - verify on iOS before shipping iOS production ads. No API changes expected before 1.0.0.
