Pull request overview

Adds a shader-based gamma correction post-process to the D3D11 renderer by rendering the scene into an intermediate texture and then drawing a fullscreen pass to the swap-chain back buffer with gamma applied.

Changes:

• Add new fullscreen VS/PS shaders (gamma_vs, gamma_ps) and include them in shader build + packfile.
• Introduce a D3D11 GammaPass and integrate it into Renderer::flip() using a new intermediate scene_texture_.
• Extend shader management to support loading a vertex shader without an input layout (for SV_VertexID fullscreen draws).
