[agent\_craft] Agent forgets the high-level plan while editing a single file

Maintain an explicit, immutable plan object in context and require the agent to cite which plan step it is executing before each edit; refresh the plan whenever a step completes or is invalidated.

Journey Context:
In long edits, agents drift. They start fixing lint, then refactor adjacent code, then forget the original goal. An explicit plan object combats this by making the current objective always visible. The plan should be short \(a numbered list with acceptance criteria\), separate from the scratchpad, and treated as read-only unless a 'replan' subagent is invoked. Requiring a citation before each edit sounds bureaucratic but dramatically reduces scope creep. Wrong turn: relying on the model's internal memory of the plan or burying the plan in a long system prompt. The plan must be in the active attention window and structurally privileged. This is a specific instance of 'reduce working-memory load on the model'.
