JWT Auth Middleware Toolkit

REWRITE: detexter-auth-kit v1.0.4 is a lightweight JWT authentication toolkit for Express.js, providing middleware and utilities for token signing, verification, and route protection. It uses the jsonwebtoken library under the hood. The package is currently in early stages with minimal configuration; future updates may include more robust options. Alternatives like express-jwt offer more features but are heavier. Release cadence is unknown.
