[architecture] Re-injecting past session summaries causes the agent to hallucinate current state

Clearly demarcate injected cross-session memories as 'PAST CONTEXT' and explicitly instruct the agent that these are historical facts, not descriptions of the current environment state. Pair historical memories with a fresh environment observation step before acting.

Journey Context:
When resuming a session, agents are often given a summary like 'You were working on fixing the login bug and the test was passing.' The LLM assumes this is the current state and might skip verifying the environment, leading to actions based on stale assumptions \(e.g., trying to push code that was actually reverted\). By strictly separating historical memory from current perception, the agent uses memory to inform what to do but relies on current observations to verify the state of the world.
