Refactor topic info ioctls to report actual endpoint count on overflow about 1 hour ago

AI Summary: This GitHub issue proposes refactoring two `agnocast` ioctls, `get_topic_subscriber_info` and `get_topic_publisher_info`, which currently return an error (`-ENOBUFS`) when the provided buffer is too small to hold all topic endpoint information. The goal is to enhance their utility by returning partial results along with metadata indicating the actual total count or if more entries exist, allowing callers to detect truncation rather than just receiving an error.

Complexity: 3/5
