v0.1.1

[0.1.1] - 2026-06-28

UI layer improvements: dynamic version display, DI consistency, shared
theme system, Markdown table rendering, recursive file tree, and expanded
test coverage.

Added

• Markdown table rendering: GFM-style tables (| col | col | with
  |---|---| separator) are now rendered as monospace, column-aligned
  text with a dashed separator line. Supports auto-sized columns,
  colon-aligned separators, escaped pipes, and missing trailing pipes.
• Shared theme system (Styles/Theme.axaml): 24 semantic color and 24
  brush resources centralized in a single resource dictionary, replacing
  30+ hardcoded color values across AXAML and C#.
• Recursive file tree: project files are displayed in a TreeView with
  expandable/collapsible directory nodes instead of a flat list. Build
  artifacts (.git, bin, obj) are excluded; empty directories are skipped;
  top-level directories are expanded by default.
• Unit tests for ChatTabViewModel (16 tests): send/cancel, streaming
  accumulation, error handling, IsGenerating state, ClearMessages,
  OnProjectChanged, ToggleExpand, Dispose.
• Unit tests for ChatViewModel (16 tests): multi-tab management, active
  tab switching, close behavior, project change propagation.
• Unit tests for MarkdownRenderer (20 tests): table rendering, existing
  markdown features regression, edge cases.
• RenderToText internal helper on MarkdownRenderer for testability.
• Shared Avalonia test infrastructure (AvaloniaTestHelper +
  AvaloniaFixture + AvaloniaTestCollection): serializes
  Avalonia-dependent tests via xUnit collection fixture to fix
  thread-safety issues with StyledElement static constructors under
  parallel test execution.

Changed

• About dialog now reads the version from AssemblyInformationalVersion
  (set by MinVer from git tags) instead of a hardcoded string.
• TemplateGalleryViewModel is now registered in the DI container and
  resolved via GetRequiredService, matching the pattern used by all
  other view models.
• All hardcoded color values in AXAML views, converters,
  ChatMessageViewModel, and MarkdownRenderer now resolve brushes via
  Application.Current.Resources with semantic resource keys.
• File tree double-click only opens files (not directories) for preview.
• OnFileDoubleTapped handles both TreeView and ListBox sources.

Fixed

• Avalonia headless test initialization race condition: multiple test
  classes initializing the headless application via static constructors
  could race under parallel test execution, causing
  StyledElement..cctor failures. Consolidated into a single
  collection fixture.
