DagNats v0.0.18 → v0.0.24. Six minors of upstream bugfixes. No breaking change in the API this template uses — server.New/server.Config, server.EmbeddedWorker and worker.TaskContext (with every method) are unchanged; the only new field is server.Config.MaxPayload, optional and defaulting to nats-server's own 1 MiB. No transitive bump was needed: the repo already pinned nats-server v2.15.0 and nats.go v1.54.0, exactly what v0.0.24 requires. Two upstream fixes matter here — v0.0.22 restores TaskContext.Metadata(), so per-step metadata reaches workers again after #652 dropped it from the dispatch path in v0.0.14 (per-step config is still never populated, so the onboarding example-todo titles keep riding the DAG input/output chain), and v0.0.20 fixes grouped-step retries never firing, which left a run stuck in running forever. v0.0.20 also requires Go >= 1.27.1; the repo is already there.
