feat(ios): iOS e2e support — Kotlin Native SDK + simulator driver + test-ios (#38)

* feat(ios): add simulator management package

* feat(testrun): add iOS platform path (simctl launch + direct TCP)

* feat(cli): add --ios-device flag and IosDevice option

* feat(sdk-ios): add Kotlin Native iOS SDK (TCP agent + POSIX socket + dispatch pauser)

* feat(folio-ios): wire SanderlingIos.start() in MainViewController

* feat(folio-ios): add test-ios justfile recipe

* fix(sdk-ios): remove unavailable C macros; manual byte swap + no-cast warnings

* fix(testrun): simctl-first launch order for iOS; Maestro init after SDK connects
