Refactor launcher startup, logging & host resolution

Improve launcher startup flow, logging, and host resolution. Key changes: add detailed startup logging and standardized preview messages; unify CLI vs GUI handling and error/result reporting (write result file when requested); refactor DeploymentLocator to a more robust host resolution (new HostResolutionResult, explicit/portable/published/debug resolution paths, legacy fallback); overhaul LauncherFlowCoordinator to better handle IPC stages, activation retries, window lifecycle, plugin/update flows and error reporting; add CommandContext helpers (IsGui/IsPreview/ExplicitAppRoot) and JSON context options; tighten async usage and ConfigureAwait calls; add better UI error handling and consistent exit codes. Several UX/debug conveniences and robustness fixes included.
