- Extract libolive-rendercore static library to minimize backend link boundary. - Add DynamicRenderer adapter with C ABI (oakgl/oakvulkan shared libs). - Make OAK_ENABLE_DYNAMIC_RENDER_BACKEND default ON with OpenGL fallback. - Implement VulkanRenderer prototype (textures, shaders, UBO blit, readback). - Add backend-neutral viewer readback path (offscreen -> QImage -> QPainter). - Refactor PluginRenderer to be renderer-agnostic; OFX plugins fall back to CPU path on non-OpenGL backends while preserving OpenGL render path. - Add Renderer::AttachOutputTexture/DetachOutputTexture and C ABI forwards. - Update docs/zh/render-backend-dynamic-plan.md for Phase 3/4/5.
