What's Changed

• feat(client): add automatic session reset and exponential retry on network drops (BoringSSL/curl 35, timeout, and closed keep-alive sockets).
• wrapped all HTTP reading and posting methods in HFRClient (get_topic_page, get_latest_topic_messages, get_post_by_id, get_quote_chain, list_mps, get_mp_page, post_reply, post_mp_reply, get_post_form_tokens, search_wiki_smilies,
  get_smiley_keywords) with transparent retry logic and socket pool refreshes.
• added configurable max_retries (default: 3) and initial_backoff (default: 0.5s) parameters to HFRClient.
