Better Auth Waitlist Plugin

The `better-auth-waitlist` package, currently at version 3.0.1, is a lightweight and production-ready plugin designed to integrate comprehensive waitlist management into the Better Auth authentication system. It offers features such as administrative approval workflows, restrictions based on email domains, and highly customizable validation for waitlist entries. The package is optimized for minimal bundle size, weighing approximately ~22 kB minified and ~3.5 kB gzipped, and lists `zod` as its only direct runtime dependency. Shipping exclusively as an ES module (ESM), it mandates a Node.js environment of version 18 or higher. Its primary differentiators include deep integration with Better Auth, flexible configuration options for various waitlist use cases (e.g., capacity limits, auto-approval, custom data fields), and client-side utilities for seamless application integration, supporting operations like joining, status checks, and admin-only actions such as listing, finding, approving, and rejecting entries.
