refactor(agent): make memory summaries cumulative (#5610)

* refactor(agent): make memory summaries cumulative

Treat the latest session summary as a replacement checkpoint, preserve it through bounded raw fallbacks, and reserve history.jsonl for Dream ingestion.

* fix(agent): preserve cumulative checkpoint context

* fix(agent): preserve memory archive prompt cache

* refactor(agent): state archive prompt positively

* refactor(agent): remove checkpoint version migration

* refactor(agent): summarize full archive context

* test(agent): align cumulative archive prompt assertion

* refactor(agent): clarify memory checkpoint contract
