Module single_timeline 

A single stateful timeline cursor

SingleTimeline walks one feed (a specific user’s posts, a specific hashtag, the mentions of a given client, …) backwards through time, yielding pages of posts via get_more_posts(). It owns:

• a crate::client::timeline::recursive_bucket_visitor::RecursiveBucketVisitor that walks the hierarchical bucket ladder for the timeline’s (BucketType, base_id);
• a post_ids_already_seen set that deduplicates across overlapping buckets and across pages (important for Sequel / ReplyToPost timelines where posts can surface from multiple places);
• a crate::client::timeline::recent_posts_pen::RecentPostsPen reference so the user’s own very recent posts appear instantly instead of waiting for the next DHT read.

Timelines never reach an end — the walk just keeps stepping further back in time on demand (a hard-earned invariant: manually triggered “fetch more” must always produce something, even if it has to go a year further back to find it).
