Allow plugins to return informational messages without the next-steps heading or indentation. Invoke each hook once and render generic messages before the shared next-steps block. Centralize grouping and formatting in PrintMessages, with a callback for template evaluation and error handling. This avoids the need for an intermediate EvaluatedMessage type and simplifies hook collection to return the original responses. Skip messages containing only whitespace while preserving empty lines within non-empty messages. Keep PrintNextSteps as a deprecated wrapper to preserve existing callers and output. Update the printer tests and remove the obsolete appendMessages helper and its tests.
