Auth internal errors are thrown by the authentication infrastructure — encryption contexts, credential vaults, token stores, session management, and provider registration. All are internal errors that should never be exposed to clients. For public-facing auth errors, see Auth Errors.

new VaultNotFoundError(entityType: string, id: string)
Example:
import { VaultNotFoundError } from '@frontmcp/sdk';throw new VaultNotFoundError('credential', 'slack_oauth');// "credential "slack_oauth" not found in vault"
