Add launcher debug settings, recovery & version fixes

Introduce a persistent LauncherDebugSettingsStore and wire it into ErrorWindow and SplashWindow so dev-mode and custom host path can be saved/loaded. Harden DeploymentLocator/FlexibleHostLocator to safely normalize and validate saved debug paths and log warnings for malformed values. Add a WaitingForShell startup state and recoverable-activation logic across App and LauncherFlowCoordinator (with registry updates) so Launcher can attach to an in-progress desktop shell rather than failing. Clean up ErrorDebugWindow UI/flow (WasAccepted flag, localization fixes, event wiring) and improve splash version population. Improve AppVersionProvider to trim surrounding quotes, robustly parse version.json via JsonDocument and read string properties; add unit tests for AppVersionProvider, DeploymentLocator and LauncherDebugSettingsStore. Also quote Exec commands in the csproj and harden scripts/Generate-VersionFile.ps1 (argument normalization, LiteralPath, error handling).
