chore(extraction): document sidecar dev alerts

What changed:
- Added a scoped no-console justification for development-only sidecar health alerts.

Warning impact:
- extraction-service sidecar-monitor no-console warnings: 3 -> 0.
- Workspace lint: 93 -> 90 warnings.

Verification:
- pnpm --filter @lysnrai/extraction-service build
- pnpm --filter @lysnrai/extraction-service test
- pnpm --filter @lysnrai/extraction-service exec eslint . --ext .ts,.tsx
- pnpm lint
