Keep Goal workflow problem reports on the goal issue

[Copilot]

Goal workflow problem handling could route blockers or framework-level problem reports into new issues. Those reports should stay on the selected goal issue as comments.

• Disable issue creation for problem paths
  • Turn off issue creation for missing-tool, missing-data, report-incomplete, no-op, and failure reporting paths.
  • Align the generated lock workflow with the source workflow configuration.

safe-outputs:
  report-failure-as-issue: false
  missing-tool:
    create-issue: false
  missing-data:
    create-issue: false
  report-incomplete:
    create-issue: false
  noop:
    report-as-issue: false

• Clarify workflow behavior

  • Add prompt guidance that blockers, protected-file fallbacks, and problem reports for a selected goal must use add_comment on selected.number.
  • Explicitly prohibit opening a separate issue for problems with the selected goal.

• Add contract coverage

  • Add tests that verify both workflow Markdown copies and the generated lock config preserve the no-new-issues reporting contract.
