/**
 * Custom Auth Adapter Factory
 *
 * Provides a minimal-config way for users with existing auth systems
 * to plug into Rebase. Only `verifyRequest` is required — everything
 * else is optional.
 *
 * @example
 * ```ts
 * import { createCustomAuthAdapter } from "@rebasepro/server-core";
 *
 * const auth = createCustomAuthAdapter({
 *   verifyRequest: async (request) => {
 *     const token = request.headers.get("Authorization")?.replace("Bearer ", "");
 *     if (!token) return null;
 *     const decoded = jwt.verify(token, MY_SECRET);
 *     return {
 *       uid: decoded.sub,
 *       email: decoded.email,
 *       displayName: decoded.name,
 *       roles: decoded.roles || [],
 *       isAdmin: decoded.roles?.includes("admin") ?? false,
 *     };
 *   },
 * });
 * ```
