Public API:
    - IntegrationError: Base exception for integration errors
    - encrypt_value, decrypt_value, is_encrypted: Credential encryption
    - ContributorIdentityService: Member/Identity linking across providers
    - BaseAPIClient: Protocol for integration API clients
    - BaseSyncService: Protocol for integration sync services
