Add DA_RenderPipelineProfile and Platform Render Profiles documentation

- Introduced DA_RenderPipelineProfile data asset to define rendering pipeline configurations for various platforms and quality tiers.
- Documented enums, structs, variables, and default preset tables for render settings.
- Created a comprehensive developer guide for setting up platform-specific render profiles, including file structure, profile creation, and integration with upscalers.
- Included validation rules, console variable references, and testing matrices for ensuring compliance with platform requirements.

 ### Purpose
-Automatically adjusts graphics, audio, and gameplay quality settings based on real-time performance metrics (frame time, draw calls, memory usage). Provides a unified interface for all other systems to scale their quality without direct awareness of the hardware. Supports manual user override via Settings menu and adaptive automatic mode. Maintains a performance budget that is dynamically allocated across subsystems.
+Automatically adjusts rendering, audio, and gameplay quality settings based on real-time performance metrics (frame time, draw calls, memory usage). **Delegates all render pipeline CVar changes to `BPC_RenderPipelineManager`** — this component focuses on monitoring performance and deciding WHEN to change quality tiers. The RenderPipelineManager handles the HOW (which CVars to execute, whether a reload is needed). Supports manual user override via Settings menu and adaptive automatic mode. Maintains a performance budget that is dynamically allocated across subsystems.
