- internal/logging now wraps log/slog; logging.format json/text finally
works (json is the documented default). Same exported API.
- New internal/metrics: /metrics on the configured metrics port with
notification gauges by status/type, queue depth, and HTTP request
count/duration labeled by mux route pattern; sampled from service
stats so the service layer stays metrics-agnostic.
- Standard grpc.health.v1 health service registered (k8s gRPC probes);
gRPC MaxRecvMsgSize bounded to match the REST 1 MB body limit.
- Dedicated health listener on health_check.port serving /health and
/readyz (probes now work in grpc-only mode); metrics, health, and
REST servers all shut down gracefully.
- main wires retry backoff, CORS, readiness checks, and TLS from config.
