- Add tree-sitter-hlsl WASM grammar (builds from tree-sitter-grammars/tree-sitter-hlsl) - Add languages/hlsl.ts extractor (based on C++ extractor) - Register .hlsl, .usf, .ush, .glsl extensions in EXTENSION_MAP - Maps all shader extensions to HLSL grammar (USF/USH are Unreal Engine HLSL variants) Enables CodeGraph to index shader files in Unreal Engine, Unity, and other HLSL/GLSL-based projects. Parses function definitions, structs, enums, includes, and function calls. Fixes colbymchenry#283 (partially — documents new language support)

.hlsl.usf.ush.glslWhy bundled WASM
tree-sitter-hlsl is not included in the
tree-sitter-wasmspackage. The WASM is pre-built usingtree-sitter build --wasmand follows the same bundling pattern aspascal,scala,lua, andluau.Tested
