  "message": "Refactor gRPC runtime services and add Node.js runtime metrics (#139)\n\nRefactor gRPC service lifecycle and add Node.js runtime metrics\n\nThis PR replaces the old per-client gRPC protocol wiring with a ServiceManager-based lifecycle and a shared grpc-js channel manager, using the Java agent core service model as structural reference while keeping Node.js-specific async behavior.\n\nIt adds Node.js runtime metric collection through MeterReportService, including process CPU, heap, RSS, external memory, and heap limit meters, with bounded buffering, configurable collection/report intervals, and deprecated runtime metric config aliases.\n\nThe gRPC lifecycle now includes explicit shutdown guards, stale callback protection, DISCONNECT handling, per-call deadlines, throttled error logging, and controlled report/flush scheduling to avoid agent-side crashes, duplicate timers, or unnecessary RPC work while disconnected.\n\nVerified with lint, build, focused config/runtime/channel tests, and manual lifecycle repros for shutdown, late grpc-js callbacks, reconnect state, and destroy/start config behavior.",
