Fetch post comments

Fetch comments for a Reddit post by URL or t3_<id> identifier. Returns the parent post (when available) and a paginated, depth-first flat list of comments that includes nested replies. Each entry's parentCommentId is null for top-level comments or points at the parent comment for replies; group on parentCommentId to rebuild the thread tree. Use the nextPageToken field from the response to retrieve subsequent pages of top-level comments (their nested replies come along automatically).
