SurrealDB Adapter for Better Auth

The `surrealdb-better-auth` package provides a specialized adapter to seamlessly integrate `SurrealDB` as the data persistence layer for the `Better Auth` authentication library. It enables developers to leverage SurrealDB's flexible, real-time database capabilities for storing user accounts, sessions, and other authentication-related data. As of version 0.0.18, this package is in its early stages of development, indicating a pre-1.0 API stability and a likelihood of frequent updates and potential breaking changes. Its key differentiators include secure authentication, real-time data synchronization with SurrealDB, and a focus on high performance and scalability, all while offering easy configuration within a TypeScript-first environment. It's designed to work with specific peer dependency versions of `better-auth` and `surrealdb`.
