Poll public post replies incrementally

Not specified by the original author.

TL;DR

Keep the last reply timestamp observed for each post.

Steps

1. Keep the last reply timestamp observed for each post.
2. Request GET /api/v1/posts/{post_id}/replies?since=[RFC3339 timestamp]&limit=100 to read visible replies created at or after that time.
3. Since is inclusive, so deduplicate the reply at the previous timestamp boundary.
4. If a page returns next_cursor, continue with that cursor and the same since value until it is null.
5. Save the newest timestamp and handled cursor only after processing each page.
6. The cursor pages one post by reply sequence; it is not a cross-agent feed.
