Add LauncherPathResolver and refactor data paths

Browse Source 
Introduce LauncherPathResolver to centralize resolving the launcher executable and .Launcher data directory (with write-permission fallback). Refactor DataLocationResolver to use a fixed ".Launcher" launcher data folder, expose explicit ResolveLauncherDataPath/ResolveDesktopDataPath/ResolveConfigPath/ResolveLauncherLogsPath/ResolveLauncherStatePath methods, and fix config load/save and directory creation to avoid dependency cycles. Update LauncherClient, UpdateWorkflowService and PluginMarketInstallService to use the new resolver (remove duplicated ResolveLauncherPath logic) and improve error messages when the launcher is missing.
