FLUTTER FIXES PLATFORM VIEW CRASHES ON IOS, SWIFT TACKLES REGION ISOLATION DIAGNOSTICS

Flutter shipped critical fixes for backgrounding platform views and test flakiness on iOS, while Swift's compiler now surfaces isolation history for data race detection.

Flutter addressed a critical crash that occurred when apps with platform views on screen were backgrounded [1]. The fix removes an abort assertion that fired during the `bringLayersIntoView` operation, resolving a race condition introduced in earlier engine changes. Alongside that, Flutter eliminated duplicate scenario registration across three separate iOS files by consolidating the declarations into a single source of truth [2], reducing the surface area for future test bugs. A third fix corrected locale testing that was failing on machines with multiple preferred languages configured [3]. Over in the Swift compiler, the focus shifted to region isolation diagnostics: the compiler now generalizes isolation-history note emission to explain how values ended up in isolated regions, providing developers with the diagnostic breadcrumbs they need to fix data race issues [4]. The team also wired up the `InOutSendingNotDisconnectedAtExit` case to emit those same notes [5]. Swift also adjusted to upstream LLVM changes around lazy submodule deserialization [6]. Across both repos, 11 commits and 8 PRs landed this period, split between iOS stabilization and compiler diagnostics.
