Add dynamic render quality settings and scaling

Browse Source 
Introduce a RenderQuality enum (Low/Medium/High) and allow users to switch quality at runtime via keyboard shortcuts. The fractal renderer now adapts its internal resolution, particle counts, and computational workload based on selected quality and real-time performance, aiming to maintain a target FPS. HUD and window title display current quality and FPS. Renderer buffers and limits are dynamically resized on window or quality changes for improved performance and flexibility.
