[frontier] Agent behavior changes catastrophically after ~50 turns due to implicit summarization

Adopt Strategic Context Refresh: proactively summarize and reset context at turn 40-45 with explicit identity re-injection, rather than letting the model's implicit compression handle it

Journey Context:
Many frameworks use 'summarize when context is full' but this creates a discontinuity. The pattern is to anticipate the cliff and do a controlled reset: compress the history into a 'memory block' and start a fresh context with system prompt \+ memory block \+ current task. This prevents the 'who am I again?' moment that happens with automatic compression. The key is proactive timing \(at 80% of context window, not 100%\) and explicit re-anchoring of identity in the new context.
