## Summary **What is the goal of this PR?** This change avoids the pattern of creating a `std::string` using `.substr` in order to compare against a file extension literal. ```c++ std::string path; if (path.length() >= 4 && path.substr(path.length() - 4) == ".ext") ``` The `checkFileExtension` utility has moved from StringUtils to FsHelpers, to be available to code in lib/. The signature now accepts a `std::string_view` instead of `std::string`, which makes the single implementation reusable for Arduino `String`. Added utility functions for commonly repeated extensions. These changes **save about 2 KB of flash (5,999,427 to 5,997,343)**. --- ### AI Usage While CrossPoint doesn't have restrictions on AI tools in contributing, please be transparent about their usage as it helps set the right context for reviewers.
