npm/fs

@npmcli/fs is a Node.js library that extends the core `fs` module with additional helper functions and polyfills for the npm CLI. It provides features like `fs.cp` polyfill for older Node versions, `fs.withTempDir` for creating and managing temporary directories, `fs.readdirScoped` for reading scoped package directories, and `fs.moveFile` for reliable file/directory moving across partitions. This library is designed for npm CLI developers and Node.js applications that need enhanced filesystem operations.
