Build the spawn:* tags for daemon-enforced lifecycle hooks. Each field emits
its tag only when set; durations serialize to Go duration strings. These are
written verbatim to the shape the Go tool uses (pkg/aws/tags.go) so a real
spored on the instance runs them — spawn-ts never executes them itself.
