// StartLaunchTemplateDaemonLite subscribes a real
// handlers_ec2_launchtemplate.LaunchTemplateServiceImpl — the same production
// code a live daemon runs (daemon/daemon_handlers_launchtemplate.go) — to
// every ec2.*LaunchTemplate* subject the gateway's NATSLaunchTemplateService
// client calls (gateway/ec2/launchtemplate/*.go, RunInstances.go's
// expandLaunchTemplate). Unlike StubSubject's static canned JSON, this
// exercises the real KV-backed CRUD and version-resolution logic, matching
// how RunInstances resolves a referenced template into effective ImageId/
// InstanceType before the per-node launch dispatch.
//
// Kept separate from StartDaemonLite (rather than folded into it) following
// StartVolumeDaemonLite's precedent: only a test that actually exercises
// launch templates should pay for wiring this service.
