 * Regression guard for #2012: AskUserQuestion is Claude Code-only — non-Claude
 * runtimes (OpenAI Codex, Gemini, etc.) render it as a markdown code block
 * instead of triggering the interactive TUI, so the session stalls.
 *
 * Every workflow that calls AskUserQuestion MUST include a TEXT_MODE fallback
 * instruction so that, when `workflow.text_mode` is true (or `--text` is
 * passed), all AskUserQuestion calls are replaced with plain-text numbered
 * lists that any runtime can handle.
 *
 * The canonical fallback phrase is:
 *   "TEXT_MODE" (or "text_mode") paired with "plain-text" (or "plain text")
 * near the first AskUserQuestion reference in the file.
