initial state (context) to include last turn's summary output so next non-new-topic turn will benefit.

[BlitzBricksterYY-db]

initial state (context) to include last turn's summary output, so it natually include:

1. context
2. previous plan
3. results with limit xxx rows
4. insights
5. SQLs

this will accelerate next turn if next turn is a refinement, continue, etc. (non-new-topic turn will benefit this)
