feat(infra): add load testing + finalize CI/CD for Go and Hono services

Load testing:
- k6 test suite for mana-sync (HTTP sync, WebSocket stress, mixed)
- 3 scenarios: mixed workload, WebSocket-only, sync throughput
- Custom metrics: push/pull latency, WS connect time, conflict count

CI/CD:
- Add 6 missing services to ci.yml: mana-sync, mana-notify,
  mana-api-gateway, mana-crawler, mana-media, mana-credits
- Add same services to cd-macmini.yml for auto-deploy
- Add mana-sync + mana-media to docker-validate.yml
- Go services trigger on shared-go/ changes
