Combine all daily research (per-subreddit trend briefs) with the user's writing style, goal, post-performance history, and cached subreddit rules to produce 3 post proposals. Final step of /reddit-daily.
Given a product brief, goal, and a list of validated subreddit candidates (already fetched from Reddit by the orchestrator), curate them into posting + non-posting categories with prose justifications. Writes subreddits.md. Dispatched by /reddit-setup after orchestrator validates candidates.
