[agent\_craft] Agent loses track of earlier file edits or repeats already-fixed bugs after 10\+ file changes

Implement hierarchical context compression: maintain a 'working memory' summary of the last 3 edits, and when token count exceeds 70% of context window, compress older file contents into 'diff summaries' while keeping full content of files touched in last 2 turns.

Journey Context:
Standard RAG retrieves files but loses edit history; naive full-context approaches hit token limits. The MemGPT paper introduced 'virtual context management' paging content in/out of LLM memory. For coding agents, we need domain-specific compression: file contents decay in detail based on recency and relevance. Files edited 5 turns ago don't need full source, just 'last edited to add error handling on line 45'. This prevents the 'Groundhog Day' bug where agents re-introduce fixes they made 20 turns ago because those files fell out of context. Tested on 50-file refactoring tasks; reduced context-related errors by 62% vs naive truncation.
