ext: JavaScript Utilities and Polyfills

The `ext` package, formerly known as `es5-ext`, is a comprehensive JavaScript utility library that provides a collection of non-standard or soon-to-be-standard language extensions and polyfills. It differentiates itself by offering these utilities in a future-proof and non-invasive manner, meaning it generally avoids polluting global prototypes without explicit action, and is designed to be compatible with ES3+ environments without requiring a transpilation step. The library is highly modular, allowing developers to import only the specific functions or objects they need, such as `globalThis`, `Object.clear`, or `String.prototype.camelToHyphen` functionality. While the package has seen recent maintenance releases (e.g., `v0.10.64` in February 2024) addressing stability issues, the latest feature-rich version is `v1.7.0`, released in August 2022. Its release cadence combines frequent bug fixes with less frequent, but impactful, feature additions, ensuring both stability and progressive enhancement capabilities.
