Conversation
Previously, the text.Deprecated() function wrote warnings to stdout (via the provided io.Writer parameter), which mixed warnings with actual command output. This made it difficult for users to redirect output cleanly or for tools to parse stdout. Changes: - Modified text.Deprecated() to write directly to os.Stderr - Added TestDeprecated() to verify stderr output - Updated test expectations to not check for deprecation messages in stdout
