Keep PM interviews usable when the MCP daemon is unavailable

[Mineru98]

Problem

Product interview flows currently depend on the MCP daemon being reachable. When the daemon is disabled or unavailable, a user asking for a PM-style interview can lose the visible question flow instead of getting a useful next step.

This is especially noticeable for natural product requests such as “I want to build a SaaS” or Korean product-idea prompts, where the expected behavior is an adaptive interview rather than a hard transport failure.

Proposed change

When the MCP daemon is unavailable and the active model is ready, let the active model generate the next ASK_USER interview question locally. The generated question should be routed through the same visible interview panel, preserve prior answers, and complete with a seed-ready handoff.

The normal MCP-backed path should still win whenever the daemon is available.

Acceptance criteria

• Natural product-building requests are routed to the PM interview workflow.
• Korean product-intent prompts are classified as PM interview candidates.
• If the MCP daemon is unavailable, the active model generates a visible ASK_USER question.
• Local fallback questions preserve the original user goal and previous answers.
• The fallback does not mask the normal live MCP path when the daemon is available.
• Completion clearly tells the user when the interview is ready for ooo seed.
