feat: implement smoketest and extend host provisioning with template linking

- Add runSmoketest mutation to automate end-to-end verification.

- Add SmoketestExecutor and HostDeleter to support automated testing and cleanup.

- Extend createHost and importHosts to allow linking templates by name or ID.

- Update docs/howtos/cookbook.md with new recipe steps and AI/MCP guidance.

- Update .junie/guidelines.md with new verification and deployment standards.

- Add src/test/template_link.test.ts and update existing tests to cover new functionality.

- Regenerate GraphQL types to match schema updates.
