ed74dae: fix(ui): make input optional on output-error tool and dynamic-tool UI message parts
validateUIMessages rejected persisted assistant messages whose output-error tool parts had no input key. This happened for any errored tool call where the SDK set input: undefined (e.g. NoSuchToolError / InvalidToolInputError): JSON serialization stripped the undefined value, and Zod 4.4+ treats a missing z.unknown() key as a validation failure (previously it was implicitly optional). The schema now matches the runtime shape produced by process-ui-message-stream, so reloading a thread that contains an errored tool call no longer throws AI_TypeValidationError.
