[avenger] Fix debug playbook coverage for empty-output failure codes #70661

Fix debug playbook diagnostic coverage

CI failure

CI run 39513543386, job Validate workflow container pins, failed make test-guidance: driver_crash needs an evidence/remedy row. The same registry also lacked coverage for secret_redaction_failure.

Fix

Document both codes with evidence and remedies, distinguishing driver crashes from engine outages and preserving secret-redaction safeguards. Tighten surrounding prose to retain the existing 2,800-word playbook budget. Only .github/aw/debug-playbook.md changed; no protected workflow files or runtime behavior changed.

Validation

• make test-guidance: all 15 tests pass, including complete diagnostic coverage and word/byte budgets.
• make agent-report-progress: passed; CLI build succeeded and impacted Go tests correctly skipped because no Go files changed.
• git diff --check: passed.
• Standalone make fmt and make lint were not run because this is a Markdown-only fix.

Limitations and feedback

git fetch origin main failed certificate verification; TLS verification was not weakened. Merging the available local origin/main reported already up to date, but remote freshness could not be confirmed. Steering issue #70655 had no comments. The configured safe-output PR transport is used because report_progress is unavailable.

To route changes like this to a review issue instead of blocking, configure protected-files: fallback-to-issue in your workflow configuration.
