) * Refactor update workflow into UpdateController Move the update orchestration out of MainWindow into a new UpdateController: startup/manual update checks, the automatic-notice policy, download, installer handoff, and the graceful shutdown from #48. MainWindow keeps only the WPF concerns (update-notice controls, status text, download-progress text) behind a new IUpdateNoticeView seam, and ISettingsHost/SettingsWindow are unchanged apart from delegating to the controller. UpdateService (SHA-256 fail-closed download) and UpdateLauncher (/IMIRROR_LAUNCH=1 silent handoff) are reused as-is; no behavior change. The controller takes injected delegates so it is unit-testable without WPF; adds 18 UpdateController tests. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Harden update download lifecycle: cleanup and shutdown cancellation Two fixes to the update workflow, built on the UpdateController extraction (#49): 1. Downloaded installers were never deleted, so %LOCALAPPDATA%\iMirror\Updates grew by one setup.exe per update forever. UpdateService.TryCleanUpDownloadedInstallers now removes leftover .exe/.download files at startup (best-effort; files locked by a still-running installer are skipped until the next start). 2. Update checks and installer downloads used CancellationToken.None, so an in-flight download raced process teardown when the user closed the app. UpdateController now owns a shutdown CancellationTokenSource that MainWindow cancels at the start of ShutdownApplicationAsync; a canceled install returns quietly without flashing the retry UI. The SHA-256 fail-closed verification and the #48 installer handoff (launch installer, then graceful shutdown, relaunch via /IMIRROR_LAUNCH=1) are unchanged. Adds 7 tests.
