Record Interactive Answer

Persist a feature-bound interactive-question pick that skipped the chat turn.

A resolved-address pick adds its layer directly (deterministic CRUD, no agent turn), so its answer never rode a prior_answer onto /chat/stream. This records it against the owning question so a reload renders the card answered. No agent run is started. A pick whose question isn't in the persisted history (a paste-injected card) records nothing and returns recorded=False.
