SurrealDB Auth Adapter

SurrealDB adapter for Better Auth (v0.2.1) — connects SurrealDB v3 multi-model database to Better Auth's authentication system via the surrealdb@^2.0.3 JS SDK. Integrates with Better Auth CLI to generate SurrealQL schema. Supports multiple ID generation strategies (ULID, UUIDv4, UUIDv7, GUID, auto) either server-side or SDK-side, and accepts both Surreal and SurrealSession instances. Requires Node.js ≥20 or Bun ≥1.2. Key differentiator: native SurrealDB identity generation and datetime handling fixes.
