Introduce a new OOBE step for "Startup & Presentation" that exposes startup and UI preferences in OobeWindow (toggles for taskbar, slide/fade transitions, fused popup, and autostart). Add HostAppSettingsOobeMerger to read/write Host settings.json (PascalCase fields) and MergeStartupPresentation behavior, plus LauncherWindowsStartupService to sync the current Launcher into the Windows Run key on Windows. Wire UI handlers, persist choices on Next, and load defaults when entering the step. Include unit tests for the merger, adjust SettingsWindow navigation pane/toggle handling, and update docs/LAUNCHER.md to describe the new OOBE step and implementation files.

* Enable centralized package versioning
Add <Project> and <PropertyGroup> with <ManagePackageVersionsCentrally>true</ManagePackageVersionsCentrally> to Directory.Packages.props to enable centralized package version management across the repository. This allows package versions to be controlled from this single file instead of individual project files.
* Migrate codebase to Avalonia 12 APIs
Apply Avalonia 12 migration changes: replace SystemDecorations with WindowDecorations and remove ExtendClientAreaChromeHints/ExtendClientAreaTitleBarHeightHint usages; update BindingPlugins removal logic (no-op); switch clipboard usage to ClipboardExtensions.SetTextAsync; update Bitmap.CopyPixels calls to the new signature. Replace TextBox.Watermark with PlaceholderText, convert NumberBox styles to FANumberBox and adjust templates, change Checked/Unchecked handlers to IsCheckedChanged, and adapt FluentIcons usages (SymbolIconSource -> FASymbol/FAFont/FluentIcon equivalents). Fix MainWindow partial classes to inherit Window and correct missing variables/fields/usings. Add migration docs/specs/tasks under .trae and include a small TestFluentIcons project for icon testing.
* Migrate to Avalonia 12 and Plugin SDK v5
Upgrade project to the Avalonia 12 baseline and Plugin SDK v5: centralize Avalonia packages, remove legacy WebView.Avalonia usage (use NativeWebView/WebView2 EnvironmentRequested), and update Fluent/Material icon/package usages. Bump multiple package/project versions to 5.0.0 and Avalonia 12.0.1, update plugin template and README/docs to SDK v5, and add PLUGIN_SDK_V5_MIGRATION.md.
Also fix runtime/behavior bugs: make DataLocationResolver use a fixed bootstrap launcher data path and avoid recursive ResolveDataRoot; add legacy-state handling and extraction in OobeStateService; and update component settings tests to reflect migrated storage (DB/backup) and reset cache for test reloads. Various csproj, tests, and docs updated to reflect the migration and ensure build/test compatibility.
* Update icon glyphs and symbol mappings
Replace and refine icon sources across settings pages and controls: many FAFontIconSource glyphs were updated to specific Seagull Fluent Icons codepoints, some FASymbolIconSource usages were replaced with FAFontIconSource, and a number of symbol-to-Symbol enum mappings were adjusted (e.g. "Bell" -> AlertOn, "Shield" -> ShieldLock). Also clarified a comment in SettingsWindow and fixed a trailing newline in StudySettingsPage. Changes standardize icon visuals and bridge FluentIcons glyphs into FluentAvalonia icon sources.
* fix.修复合并产生的问题。
Introduce privacy/telemetry support: add PrivacyConfig and PrivacyAgreementState models, and a PrivacyAgreementService that saves/validates agreement state with HMAC integrity protection (privacy-agreement.state.json). Update AppJsonContext to include new types. Extend OOBE UI (OobeWindow.axaml/.cs) with a Data Location redesign and a new Privacy step (telemetry toggles, telemetry ID, agreement checkbox) and wire up handlers to save privacy-config.json and agreement state. Add a PrivacyPolicyWindow using Markdown.Avalonia to display the privacy policy; add CommunityToolkit.Mvvm and Markdown.Avalonia package references.

* 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.
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).
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.
Add automatic release version stamping and multiple launcher reliability improvements. The Release workflow now runs scripts/Set-ReleaseVersion.ps1 in build jobs to inject tag-derived Version/AssemblyVersion into project metadata; several .csproj/Directory.Build.props and app.manifest files were changed to use a dev placeholder. Introduced AppVersionProvider (and related runtime metadata) to centralize version resolution and updated DeploymentLocator to use it and to prefer package-root/version.json. Launcher startup flow was hardened: added startup success tracking, public-activation recovery path, improved success/fallback semantics, and related IPC handling. UI/UX fixes include OOBE entrance/exit animation improvements (scaling-aware, concurrent fade+translate) and minor window lifecycle reorder in DesktopShellHost. CommandContext now recognizes restart and key=value args. New DesktopTrayService and .trae spec files (spec, checklist, tasks) document shell/tray hardening work. Miscellaneous logging, comments and housekeeping edits across launcher and shared contracts to support the above.
