Session Context: Summary Mode

"""
Session Context: Summary Mode
=============================
Session Context tracks the current conversation's state:
- What's been discussed
- Key decisions made
- Important context

Summary mode provides lightweight tracking - a running summary without goal/plan structure.

Compare with: 3b_session_context_planning.py for goal-oriented tracking.
