Interface Errors

Interface errors represent failures surfaced at the public API boundary. DataDesignerGenerationError wraps dataset generation failures from create() and preview(), DataDesignerEarlyShutdownError identifies generation runs that terminate early without producing records, and DataDesignerProfilingError wraps profiling failures from those methods.

These errors inherit from data_designer.errors.DataDesignerError, allowing callers to catch either specific interface failures or the project-wide base error type.
