[architecture] Agent losing critical constraints or user intent after a handoff to another agent

When handing off, the active agent must generate a structured 'handoff summary' containing: 1\) Original user goal, 2\) Work completed so far, 3\) Remaining constraints, 4\) Exact next steps. Do not rely solely on passing the raw chat history.

Journey Context:
When a task moves from Agent A to Agent B, developers often just pass the raw chat history. However, LLMs suffer from the 'lost in the middle' phenomenon; critical early constraints \(e.g., 'use Python 3.8', 'do not use external APIs'\) get ignored by Agent B. A forced, explicit summarization step at the point of handoff ensures the most salient context is promoted to the top of Agent B's prompt window, preventing the receiving agent from violating original constraints.
