-Session Compaction with Fact Extraction — #748
-
-Before compressing a long conversation, extracts durable facts
-(user preferences, corrections, project details) and saves them
-to the fact store. Then compresses the conversation.
-
-This ensures key information survives context limits.

-Usage:
-    from agent.session_compaction import compact_session
-    
-    # In the conversation loop, when context is near limit:
-    compact_session(messages, fact_store)
