Session Context: Summary Mode (Deep Dive)
=========================================
Running summary of conversation state.

Summary mode maintains a running summary of the conversation that
persists across reconnections. Each turn, the summary is updated
to include the new information.

Compare with: 02_planning_mode.py for goal/plan tracking.
See also: 01_basics/3a_session_context_summary.py for the basics.
