MongoDB Client-Side Encryption Module

The `mongodb-client-encryption` package is the official Node.js wrapper for `libmongocrypt`, a core library enabling Client-Side Field Level Encryption (CSFLE) for MongoDB. It is not intended for standalone use by application developers, but rather as an internal dependency of the `mongodb` Node.js driver to provide robust encryption capabilities. The current stable version is v7.0.0, released in November 2025. Releases typically align with major and minor versions of the main `mongodb` driver, with new features and breaking changes often following driver updates. Its key differentiator is providing the native bindings and core encryption logic for CSFLE, integrating seamlessly with the `mongodb` package to allow developers to encrypt sensitive data before it leaves the application, maintaining data privacy without sacrificing queryability.
