// Bump tonic's default 4 MiB receive cap. A single agent
// window emits ~1000 series, each carrying a typed
// DDSketch / KLLSketch / ... state — the full-state
// payloads run 17+ MiB at the cardinalities the e2e
// harness uses. With the default cap, the gateway's
// OTLP exporter retries forever with
// `decoded message length too large`. Match the
// gateway/agent receiver caps (`max_recv_msg_size_mib: 64`
// in their YAMLs) so all three tiers agree.
