Daily Reddit Digest：按偏好自动汇总子版块动态

• Subreddit list is curated and grouped by theme.
• Define digest schedule and max items per section.

1. Fetch top/new posts per subreddit with score and comment count.
2. Deduplicate cross-posts and cluster similar topics.
3. Generate concise summary with links and why-it-matters notes.
4. Deliver digest in one message; keep raw links as appendix.

• Rate limits may require staggered fetch windows.
• NSFW/community-rule filtering should be explicitly configured (needs verification).
