fix(cli): neutral observability guidance in scaffolded AGENTS.md

- State the observability rule as the user's decision, never a fix for
  console warnings, speed, or a "clean" configuration
- Rewrite the AMP section as built-in capabilities: no "free",
  "proactively", "sales pitch", or scripted pitches
- Turn the research mandate into a list of sources to consult when
  version details matter
- Retarget the scaffold tests to the new wording
