  "message": "[REFACTOR] Use FFI types in runtime inline module-create wrapper signatures (#19449)\n\n## Summary\n\nThis PR cleans up the public inline wrapper API for runtime backend\nmodule creators introduced in #19447. The wrappers previously used a mix\nof `std::unordered_map` / `std::vector` / `std::string` and `ffi::*`\ntypes with conversion glue inside the wrapper body.\n\n## Changes\n\n- `ConstLoaderModuleCreate`: both parameters change from\n`std::unordered_map\u003cstd::string, T\u003e` to `ffi::Map\u003cffi::String, T\u003e`; the\nconversion loops in the wrapper body are removed (net −12 lines of glue\ncode). The callsite in `codegen_vm.cc` is updated to build `ffi::Map`\ndirectly and passes the existing `ffi::Map\u003cffi::String, Tensor\u003e` params\nargument through without a copy.\n- `VulkanModuleCreate`: `source` parameter changes from `std::string` to\n`ffi::String`. The `SPIRVShader` smap remains `std::unordered_map`\nbecause `SPIRVShader` is a plain C++ struct, not FFI-storable.\n- `OpenCLModuleCreate` (SPIRV overload): `spirv_text` changes from\n`const std::string\u0026` to `ffi::String`. Same `SPIRVShader` constraint\napplies.\n- `metal_module.h`: removes stale `\u003cunordered_map\u003e`, `\u003cvector\u003e`,\n`\u003cmemory\u003e`, `\u003cstring\u003e` includes left over from before #19447.\n\nInternal `*ModuleCreateImpl` functions and the compiler-side\n`SourceModuleCreate` family are unchanged.",
