Significantly improves the stability, performance, and visual quality of the ncurses renderer.
**Renderer Improvements (`clay_renderer_ncurses.c`):**
* **Flicker Reduction**:
* Removed `erase()` call at the start of the frame to enable differential rendering.
* Implemented "Dirty Check" optimizations for Rectangles, Borders, and Text. The renderer now reads the existing screen content (using `mvinch`, `mvin_wch`, `mvin_wchnstr`) and only issues draw commands if the content or color differs.
* Hardened Rectangle dirty check to mask out volatile attributes (comparing only `A_CHARTEXT | A_COLOR`), preventing false-positive redraws caused by internal terminal flags.
* **Memory Safety**:
* Fixed internal ncurses memory leaks by calling `delscreen(set_term(NULL))` in `Clay_Ncurses_Terminate` to properly free the default screen wrapper.
* **Visual Features**:
* Added support for **Rounded Corners**: Borders with `cornerRadius > 0` now render using Unicode arc characters (`╭`, `╮`, `╯`, `╰`).
* Upgraded standard borders to use full Unicode box-drawing characters.
**Example Application Updates (`ncurses-example/main.c`):**
* **Layout Stability**:
* Refactored all layout dimensions and gaps to use `CLAY_NCURSES_CELL_WIDTH` (8) and `CLAY_NCURSES_CELL_HEIGHT` (16) macros, ensuring strict grid alignment.
* Fixed vertical jitter in "Profile Icon" and text headers by enforcing exact height multiples and top-alignment, eliminating sub-pixel rounding errors during scroll.
* **New UI Elements**:
* Added a **Floating Help Modal** (toggled via 'H') to demonstrate Z-ordering and localized input handling.
* Added "Server Status" progress bars to the Sidebar to demonstrate percent-based sizing and colored rectangles.
* Added "Mixed Border" examples to the Sidebar to showcase the new rounded corner capabilities.
* Added "Black" background constant usage for cleaner code.
