SDK prompt suggestions no longer reuse a cached shortcut and now always generate fresh

What

When the SDK generates a suggested next prompt for a turn, it used to first check a cached value (promptSuggestion.turnBriefNext) tied to the last assistant message, and only generate a fresh suggestion if nothing was cached. That caching shortcut has been removed, so prompt suggestions are now always generated in full each time.

Why

This means SDK-generated prompt suggestions are computed fresh rather than potentially reused from a stale cached value.
