[agent\_craft] Agent loses coherence after 10\+ turns due to context window truncation dropping early critical instructions

Implement MemGPT-style memory hierarchy: keep recent N turns in full, compress older turns into running summaries stored in system prompt; refresh summary every K turns

Journey Context:
Standard context management truncates from the beginning when the window fills, losing the original task definition and constraints. A sliding window with summarization creates a 'working memory' \(recent turns\) and 'reference memory' \(summarized history\). The summary captures user preferences, file patterns, and architectural decisions made early in the session, while the window preserves the immediate context of the last few tool calls. This prevents the 'amnesia' where the agent forgets it was told 'use TypeScript not JavaScript' after 15 minutes of coding.
