Fix advisor analysis echoing instructions and ignoring user feedback

- Skip the analysis pass entirely when feedback_prompt is provided.
  The user already described what is wrong; running analysis is redundant
  and was producing the echoed instruction text as its output. Repair pass
  still runs with the feedback in OPTIONAL_NOTE.
- Rewrite the analysis prompt output instruction to use a placeholder
  format (<your specific analysis...>) instead of content words the model
  can echo back verbatim.
