Switch whiteboard note storage from legacy DB rows to per-note JSON files and add migration support. Update WhiteboardNoteSnapshot schema (version bump, viewport, canvas, expires, PathSvgData) and change IWhiteboardNotePersistenceService.SaveNote to return bool to surface write failures (e.g. read-only files). Implement file-based WhiteboardNotePersistenceService with legacy DB migration/cleanup, retention handling, and logging. Add comprehensive unit tests for persistence, stroke path builder, SVG import and viewport helper. Also add ThirdParty/DotNetCampus.InkCanvas project and reference it in the main csproj, and bump PostHog package to 2.6.0.
Introduce support for toggling the system chrome on Windows using Harmony patchers. Adds Lib.Harmony.Thin to package props and project, new patcher infrastructure (ChromePatchState, PatcherEntrance) and two Harmony patches that disable FluentAvalonia's Windows chrome when configured. Program.cs now loads the chrome setting and installs patchers conditionally on Windows/x86-x64. Settings viewmodel and view updated: expose IsWindowsOs, require restart on appearance changes, migrate SettingsWindow to FAAppWindow and adapt titlebar/layout (include Windows caption placeholder and footer menu items). Also add a .gitkeep and a build log file.
Update workspace settings and dependency versions, plus small service fixes. .arts/settings.json adds editor clawMode and activityBar location. Directory.Packages.props upgrades many packages (e.g. Avalonia to 12.0.2, CommunityToolkit.Mvvm, Downloader, Sentry to 6.4.1, Microsoft.* previews, and more). ResumableDownloadService renamed ResumeDownloadIfCan to EnableAutoResumeDownload. SentryCrashTelemetryService now adds the log-tail as an attachment via scope.AddAttachment(byte[], name, contentType) instead of creating an Attachment object.

* 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.
