fs-jetpack: Enhanced File System API

fs-jetpack provides a more convenient and opinionated API for common file system manipulations, designed as an alternative to Node.js's native `fs` module and `fs-extra`. It is particularly well-suited for scripting, tooling, and build pipelines. Currently at stable version 5.1.0, the library has an active development pace with several minor and major releases in recent years, indicating ongoing maintenance and feature additions. Key differentiators include the ability to create multiple independent Current Working Directories (CWDs) for an object-oriented approach to file operations, first-class support for JSON serialization/deserialization, automatic handling of `ENOENT` errors (creating parent directories as needed and returning `undefined` for non-existent reads), and a consistent `method()` (synchronous) and `methodAsync()` (promise-based asynchronous) naming convention, which deviates from standard Node.js patterns but aims for clarity within the library.
