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
