[synthesis] Multi-agent code review introduces new bugs because the fixing agent loses the review context

Pass structured diff context alongside natural language reviews. Instead of Agent A just receiving 'fix the off-by-one error', Agent A must receive the exact lines to change and the original reviewer's logical chain, and must output a diff rather than a full file rewrite.

Journey Context:
In multi-agent systems, Agent B reviews code and suggests a fix. Agent A applies the fix but often misunderstands the review context because natural language summaries lose precision. Agent A rewrites a larger chunk than necessary, introducing new bugs. The failure is a context precision mismatch between the reviewer and the actor. Passing structured diffs and forcing localized changes prevents the actor from drifting from the reviewer's intent.
