Inject diagnostic into repair system prompt in Full mode

When Pass 1 generates a diagnostic, append it to the system prompt of
Pass 2 so the LLM has the session root-cause analysis at the highest
priority level rather than only as a user-message field. The analysis
remains in the user message too for reference.
