Add cbt/gfx layer (pipeline + render_target) inspired by Sokol but C++-friendly with RAII and pipeline_desc. Supports building full graphics pipelines (VS/IA/raster/PS/OM), render-to-texture (FBO), and post-processing steps (scene -> RT -> fullscreen quad with sampler + vignette). - Depth/state/viewport/texture cleanup for reliable scene switching. - Updated cube/sphere to demonstrate (sphere uses RT+post). - Vulkan backend easy via PIMPL in impl (same public API). - Fixed depth test, viewport restore, and state leakage on switch. Followed coding conventions (snake_case, trailing returns, east const, include order, no ; after ns/class, etc.).
