Get a subreddit's posts

Fetch one page of posts from a single subreddit, the community-monitoring primitive. subreddit_name is the name without the r/ prefix. sort defaults to the subreddit's own front-page order (best); use sort=new for monitoring. sort=top and controversial need a range, but the window is currently not applied upstream on this feed: top returns the subreddit's all-time top posts whatever range says (time-windowed tops are a known gap here; reddit_search's range DOES work for keyword queries). Costs 4 credits per page; a cursor page is a NEW call priced the same way. Reddit splices about one promoted ad into every feed page; these are dropped by default, so set include_promoted=true only when ads ARE the data you want (ad intelligence, who targets this community) -- kept ads carry is_promoted=true. Returns post summaries (title, author, upvotes, comment_count, created_at, permalink, id) with a cursor for older posts; bodies and discussions come from reddit_get_post with the returned ids. For keyword search across all of Reddit use reddit_search; this tool takes no query.
