feat: Add ncurses renderer and example
- **Renderer**: Implemented `clay_renderer_ncurses.c` supporting rectangles, text, borders, and clipping using standard ncurses plotting. - **Example**: Added `examples/ncurses-example` demonstrating a scrollable "Social Feed" UI with keyboard navigation. - **Build**: Added `CLAY_INCLUDE_NCURSES_EXAMPLES` option to root `CMakeLists.txt` and integrated the new example. - **CompConfig**: Updated `.gitignore` to strictly exclude `build/`, `_deps/`, and other standard CMake artifacts.
