Owner

Part of epic #542 (from #186). Design + code citations are in the epic; read it first.

Size: S (1-2 d)

Vendor ReShade's effect compiler and prove it produces SPIR-V our device accepts, before any runtime work.

Scope

Vendor crosire/reshade source/effect_* (lexer, preprocessor, parser_exp/stmt, symbol_table (+ intrinsics .inl), expression, codegen.hpp, codegen_spirv.cpp, module.hpp, token.hpp) at one pinned release, plus Khronos spirv.hpp + GLSL.std.450.h. Put them in indra/newview/vkgfx/third_party/reshadefx/ with LICENSE (BSD-3) + NOTICE and a README naming the upstream commit.
Add a static lib target, outside the PCH. Must build on linux-releaseos and windows-cross (clang-cl).
Add a small dev tool or hidden debug command: preprocess + compile a .fx with given defines (__RESHADE__, __RENDERER__=0x20000+, BUFFER_*), dump the module (techniques / passes / textures / samplers / uniforms + offsets / spec constants), write .spv, run spirv-val --target-env vulkan1.3 if present, and vkCreateShaderModule on the live device.
Ship our ReShade.fxh (CC0 upstream copy) + a clean-room ReShadeUI.fxh (upstream has no licence).
Run it locally over SweetFX (MIT), prod80 (MIT), crosire/reshade-shaders samples, and, for information only and not bundled, qUINT / iMMERSE free.

Done when

reshadefx builds in-tree on Linux + windows-cross; licence/credits in place (About + NOTICE).
Compile report posted here: per pack, compiled / failed / why. Gate: ≥ 90% of SweetFX + prod80 + reshade-shaders samples compile, pass spirv-val, and create shader modules without validation-layer errors.
Go/no-go for P1 recorded in the epic. On no-go: list the blocking codegen issues and the fallback (own GLSL format for built-ins only).
