fix: apply clang-format and exclude third-party libraries from formatting checks

- Applied clang-format to fix formatting violations in TUI and other source files
- Updated CMakeLists.txt to exclude src/lib/* from format targets to prevent third-party library violations
- Fixes clang-format violations in chat_tui.cc, tui.cc, and unified_layout.cc
- All source files now pass format-check target

  * ============================================================================
  * UPDATE NOTICE (October 2025): Tests need rewrite for DungeonEditorV2
  * ============================================================================
- * 
+ *
  * These tests were written for the old monolithic DungeonEditor but need to be
  * updated for the new DungeonEditorV2 card-based architecture:
- * 
+ *
  * OLD ARCHITECTURE:
  * - Single "Dungeon Editor" window with tabs
  * - Object Selector, Canvas, Layers all in one window
  * - Monolithic UI structure
- * 
+ *
  * NEW ARCHITECTURE (DungeonEditorV2):
  * - Independent EditorCard windows:
  *   - "Dungeon Controls" - main control panel
@@ -35,14 +37,14 @@
  *   - Individual room cards (e.g., "Room 0x00###RoomCard0")
  * - Per-room layer visibility settings
  * - Dockable, closable independent windows
- * 
+ *
  * REQUIRED UPDATES:
  * 1. Change window references from "Dungeon Editor" to appropriate card names
  * 2. Update tab navigation to card window focus
  * 3. Update object placement workflow for new ObjectEditorCard
  * 4. Update layer controls for per-room settings
  * 5. Update room selection to work with new room cards
- * 
+ *
  * Current Status: Tests compile but may fail due to UI structure changes.
  * See: test/e2e/dungeon_editor_smoke_test.cc for updated test patterns.
