Update project

Controls response visibility and identity disclosure.

• transparent — All community members can see exactly who answered what for every question.
• semi-private — Only the project creator and community admins can view individual responses (who answered what). The rest of the community sees aggregated results only if the creator chooses to share them.
• anonymous — Respondent identity is hidden from everyone, including the creator and admins. Data is pseudo-anonymous: answers are recorded but not linked to a user ID or display name, unless a respondent volunteers that information in an open-text answer. Caveat: XP and achievements can still be granted in anonymous projects, so participation is not entirely hidden — particularly relevant in small communities.

Enable or disable quiz/scoring mode. When true, question blocks may carry correct_answer_index, when_correct, when_incorrect, and per-option score_values. Must be set before writing a script that uses score variables — without it, score_values weights are silently ignored and [score]/[correct_answers] variables render as literal [brackets]. Do not also set rewards.use_xp: true when using an in-survey give_xp action block with a source_key — that combination awards XP twice.
