Research direction
Examine existing clang tidy checks for similar transformations in the LLVM source code, particularly under clang tools extra/clang tidy/. Look at the comments in the issue for any design discussions or constraints. The transform should replace calls to memcpy with std::copy, ensuring type safety and proper include directives. Start by understanding how other checks register and implement replacements.
