Summary

Adds topic_memory_node to saltybot_social
Subscribes /social/conversation_text (String, JSON {person_id, text})
Keyword extraction pipeline: lowercase → strip punctuation → filter (alpha + length) → remove English stop words → deduplicate → cap at max_keywords_per_msg
PersonTopicMemory: ordered rolling list, dedup with recency promotion (duplicates move to front), capped at max_topics_per_person, evicts oldest when full
Stale-person pruning: removes persons idle for > prune_after_s (default 30 min; 0 = disabled)
Publishes JSON on /saltybot/conversation_topics on each incoming utterance:
{"person_id": "alice", "recent_topics": [...], "new_topics": [...], "ts": ...}
Enables recall: recent_topics (most-recent first) can answer "last time you mentioned X"
71/71 tests passing

Adds topic_memory_node to saltybot_social:
- Subscribes /social/conversation_text (String, JSON {person_id, text})
- Extracts keywords via stop-word filtered pipeline:
    lowercase -> strip punctuation -> filter length/alpha -> remove
    stop words -> deduplicate -> cap at max_keywords_per_msg
- Maintains per-person rolling topic history (PersonTopicMemory):
    ordered list, dedup with recency promotion, capped at
    max_topics_per_person, evicts oldest when full
- Prunes persons idle for > prune_after_s (default 30 min; 0=disabled)
- Publishes JSON on /saltybot/conversation_topics on each utterance:
    {person_id, recent_topics (most-recent first), new_topics, ts}
- Enables recall like 'last time you mentioned X'
- 71/71 tests passing
