fix(workflow): add plain-text fallback for AskUserQuestion on non-Claude runtimes (#2042)

AskUserQuestion is a Claude Code-only tool. When running GSD on OpenAI Codex,
Gemini CLI, or other non-Claude runtimes, the model renders the tool call as a
markdown code block instead of executing it, so the interactive TUI never
appears and the session stalls without collecting user input.

The workflow.text_mode / --text flag mechanism already handles this in 5 of
the 37 affected workflows. This commit adds the same TEXT_MODE fallback
instruction to all remaining 32 workflows so that, when text_mode is enabled,
every AskUserQuestion call is replaced with a plain-text numbered list that
any runtime can handle.

Fixes #2012

When TEXT_MODE is active, replace every `AskUserQuestion` call with a plain-text numbered list and ask the user to type their choice number. This is required for non-Claude runtimes (OpenAI Codex, Gemini CLI, etc.) where `AskUserQuestion` is not available.
