[architecture] Summarizing previous agent outputs into a massive text block that overwhelms the next agent's context window

Implement structured state reduction \(e.g., extracting only modified file paths and function signatures\) rather than narrative summaries when handing off between agents.

Journey Context:
To maintain continuity, developers pass a 'history' of what the previous agent did as a long natural language summary. By agent 3 or 4, this summary consumes the entire context window, pushing out the actual system prompt or task instructions. Instead of narrative summaries, agents should output structured diffs or metadata \(e.g., files\_modified: \['a.py'\], status: 'success'\). The tradeoff is loss of nuanced reasoning context, but it preserves the receiving agent's ability to actually follow its instructions.
