Introduce a new update subsystem: shared contracts for manifests, messages, paths and state (LanMountainDesktop.Shared.Contracts.Update). Add IPC and reporting infrastructure for installer progress (IUpdateProgressReporter, LauncherUpdateProgressIpcServer, NullUpdateProgressReporter) and integrate progress/complete reporting into UpdateEngineService. Add multiple update service components and providers (CompositeManifestProvider, GithubReleaseManifestProvider, PlondsApiManifestProvider, UpdateDownloadEngine, UpdateOrchestrator, UpdateInstallGateway, CLI launcher bridge, launcher bridge interfaces, observable helper, state store, progress subject, JSON context). Update settings and models to support UseGhProxyMirror and PLONDS/GitHub fallback logic, plus localization strings and UI/viewmodel files for update settings and progress. Misc: installer script tweak and a small change in Plonds generator. This adds end-to-end support for checking, downloading and reporting update progress and results.

* Resolve dev paths and fix splash UI thread
Compute a solutionRoot and expand development search paths (LanMountainDesktop and dev-test) in DeploymentLocator, add logging when scanning/finding hosts, and return distinct full paths. Ensure backward-compatible path checks. Fix cross-thread UI calls: invoke splashWindow.DismissAsync on the UI thread in LauncherFlowCoordinator, and make SplashWindow.DismissAsync ensure it runs on the UI thread before closing (simplified Close call). These changes improve development host discovery and prevent UI-thread access issues during shutdown.
* Add configurable data location (portable/system)
Introduce support for choosing and resolving the application's data root (system user dir vs. portable app folder). Adds DataLocationConfig model, DataLocationResolver (load/save/resolve/migrate), a UI prompt (DataLocationPromptWindow) and an OOBE step (DataLocationOobeStep) to let users pick and optionally migrate existing data. Wire the chosen data root into the launcher flow and host launch plan (forwarded via --data-root and LMD_DATA_ROOT), and add AppDataPathProvider to let runtime services read the effective data root (initialized in Program.Main). Update various services (logging, settings, DB, plugin/market, startup registry, etc.) to use the new provider/resolver and register the config type in the JSON context. This enables portable installs, safe migration, and runtime overrides via CLI or environment variable.
* Add dev/debug startup flow and launch profiles
Handle design-time initialization and add a developer debug startup path: App now skips normal startup when in design mode and shows a DevDebugWindow when running in debug (unless a preview or apply-update command). CommandContext.IsDebugMode is extended to include DOTNET_ENVIRONMENT=Development via a new IsDevelopmentEnvironment helper. Program.Main and BuildAvaloniaApp are made public to aid tooling. Added multiple launchSettings profiles for debug and preview commands that set DOTNET_ENVIRONMENT=Development to simplify IDE debugging and UI previewing.
* Simplify splash to fade; add themed about banners
Simplify splash startup visuals by removing the multi-mode/slide behavior and always using a fade animation. Update App to create SplashWindow without a StartupVisualMode parameter and remove related fields, layout configuration, slide animation, and easing helpers from SplashWindow. Clean up unused using. Replace the single about_banner asset with theme-aware variants (about_banner_dark.png and about_banner_light.png), delete the old about_banner.png, and update AboutSettingsPage to use a DynamicResource ImageBrush (AboutBannerBrush) that selects the appropriate banner per theme.
* Use AppJsonContext for startup state serialization
Switch serialization to the source-generated System.Text.Json context: add JsonSerializable(typeof(StartupAttemptRecord)) to AppJsonContext and replace the previous JsonSerializerOptions-based Serialize/Deserialize calls with AppJsonContext.Default.StartupAttemptRecord. Also remove the now-unused SerializerOptions field. Additionally, update .gitignore to exclude /test-aot-publish.
* Add OOBE redesign, theme & data location support
Introduce a redesigned OOBE flow and data-location/theme support across the launcher. Adds a new ThemeService for applying light/dark and accent colors; integrates FluentIcons.Avalonia package for icons. Overhauls OobeWindow (UX animations, typing effect, multi-step theme and data-location pages, Monet options, and final welcome step) and its code-behind to handle step navigation, accent selection, and data-location resolution. Adds DataLocation UI and handlers (DataLocationPromptWindow changes, DataLocation resolver usage) and wires a DevDebug UI for toggling/opening the data-location page. UpdateEngineService now resolves the launcher root via DataLocationResolver. Misc: update various view models, localization entries and remove TrimmerRoots.xml.
* Refactor data location paths and add background service
Refactor DataLocationResolver to centralize data path resolution (ResolveLauncherDataPath, ResolveDesktopDataPath, ResolveConfigPath, ResolveLauncherLogsPath, ResolveLauncherStatePath) and replace usages of the previous ".launcher" layout with a "Launcher" folder. Update API: LoadConfig/SaveConfig reorganized and ApplyLocationChoice now accepts an optional custom path and migration flag; migration logic updated accordingly. Update dependent services and views (Logger, DeploymentLocator, UpdateEngineService, OobeStateService, StartupAttemptRegistry, LauncherDebugSettingsStore, OobeWindow) to use the new resolver APIs and paths. Add LauncherBackgroundService to load/validate/cache a custom splash background image and wire it into SplashWindow (AXAML/Axaml.cs) with UI placeholders and overlay. Misc: minor cleanup of Oobe/Splash XAML and related code adjustments and logging improvements.
Implement startup visual behavior, de-duplicate startup attempts, and improve failure UX.
Key changes:
- Add spec and docs for startup visuals and timing contract (.trae/specs and docs/LAUNCHER_STARTUP_VISUALS.md).
- Introduce StartupVisualPreferences contract and resolver; create SplashWindow via resolved mode.
- Add StartupAttemptRecord model and a file-backed StartupAttemptRegistry to persist and coordinate in-progress startup attempts (attach/adopt, soft/hard timeouts, IPC/connect state, lifecycle updates).
- Update LauncherFlowCoordinator to: adopt/attach to existing attempts, track IPC connection and soft/hard timeouts (30s/120s), show delayed UI state, attempt foreground recovery via public IPC, compose detailed launch result metadata, and mark registry states (soft timeout, detached waiting, succeeded, failed).
- Add TryActivateExistingInstanceAsync to attempt activating an existing desktop via IPC.
- Change failure flow: ShowFailureWindowAsync now returns user choice; ErrorWindow updated to present Activate/Wait/Open Logs/Exit semantics and new layouts/styles; improved button wiring and debug/dev mode handling.
- Add UI and resource tweaks (ErrorWindow and SplashWindow changes), project asset link for nightly logo, and unit tests for StartupVisualPreferences.
These changes prevent duplicate desktop processes during slow startups, provide clearer UX for delayed startups, and persist startup attempt state across Launcher invocations for safer recovery/attach behavior.
Convert the settings window into an independent top-level window with its own taskbar icon and open-or-focus semantics. Removed Owner/anchor/toggle semantics from SettingsWindowService and added ScreenReferenceWindow for centering; settings windows now ShowInTaskbar = true and are truly destroyed on close. Added SettingsWindowPlacementHelper and tests for placement/centering. Main window now respects an AppSettingsSnapshot.ShowInTaskbar flag (new setting exposed in GeneralSettings UI) and slide/visibility animations and "back to Windows" behavior no longer affect the independent settings window. Updated various callers to use OpenIndependentSettingsModule, adjusted window transitions/X offsets, and added/updated spec files documenting the feature and animation boundary.
