Note

Reduce peak memory by clearing large JSON-RPC Result fields ASAP and unmarshalling only error fields; minor test timing tweaks.

• JSON-RPC memory optimizations
  • Parse error-only structures in CheckResponseError and CheckResponseErrorForJsonRpcBatch to avoid allocating large result payloads (protocol/chainlib/chainproxy/rpcInterfaceMessages/jsonRPCMessage.go).
  • After converting responses, immediately clear large Result fields to enable GC:
    • In ConvertJsonRPCMsg, set rpcMsg.Result = nil post-conversion.
    • In client batch handling (rpcclient/client.go: BatchCallContext), nil resp.Result after unmarshalling into targets.
    • In proxy paths (protocol/chainlib/jsonRPC.go):
      • Batch: convert elements then set batch[idx].Result = nil; after marshaling replies, clear replyMsgs[idx].Result.
      • Single call: after ID validation, set rpcMessage.Result = nil; after marshaling, clear replyMsg.Result.
• Tests
  • Adjust smartrouter mock ticker durations to 10s to align with new processing timing (protocol/rpcsmartrouter/smartrouter_relay_state_machine_test.go).
