Hi.

I have a question wheather it is possible to output a framebuffer color attachment texture to the front buffer instantly, without drawing a screen aligned quad in front buffer that samples this attachment.

No.

Only render buffers can be presented.

You created one at initialization internally when you called (on Windows®) ::SetPixelFormat(). Swap it while bound (it may not need to be specifically bound on Windows®). For Windows® that means ::SwapBuffers().
