/**
 * Clerk Authentication Provider
 *
 * Supports Clerk's session-based and JWT authentication.
 * Can validate both JWT tokens and session tokens via Clerk API.
 *
 * Features:
 * - JWT validation using Clerk's JWKS
 * - Session token validation via Clerk API
 * - User profile fetching
 * - Organization support for multi-tenant apps
 *
 * @example
 * ```typescript
 * const clerk = new ClerkProvider({
 *   type: "clerk",
 *   publishableKey: "pk_test_...",
 *   secretKey: "sk_test_..."
 * });
 *
 * const result = await clerk.authenticateToken(sessionToken);
 * if (result.valid) {
 *   console.log("Authenticated user:", result.user);
 * }
 * ```
