Implements Task 11: Extend GET /contacts/:id to include phones, emails, and addresses arrays. Each multi-value field is queried from its respective table (contact_phones, contact_emails, contact_addresses) and mapped to camelCase response format with isPrimary boolean conversion. Tests: 2 new tests (contact with multi-values, empty arrays) TDD workflow: RED → GREEN → Commit Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
