Add to-questionnaire skill (in-progress)

A user-invoked skill that turns a decision you can't fully answer into a
Markdown discovery questionnaire to hand to one person async, or fill out
over a meeting.

Its defining move: it grills you about the *send* (who it's going to, what
you need back), never the subject — sidestepping the "I don't know, I don't
know" spiral you'd hit if it interrogated you on the very knowledge you're
offloading. The written questions then target the gap between what the
recipient knows and what you need.

Landed in in-progress/ to shake out over a few real sends before promoting.
