Bo-Yi Wu ec07b8c00b perf: reduce runner-to-server connection load with adaptive reporting and polling
- Replace fixed 1s RunDaemon timer with event-driven select loop using
  separate log (3s) and state (5s) tickers for periodic flush
- Add batch-size threshold (default 100 rows) to flush logs immediately
  during bursty output like npm install
- Add max-latency timer (default 5s) to guarantee single log lines are
  delivered within a bounded time
- Trigger immediate flush on step transitions (start/stop) and job
  result for responsive frontend UX
- Skip ReportLog when no pending rows and ReportState when state is
  unchanged to eliminate no-op HTTP requests
- Replace fixed-rate polling with exponential backoff and jitter to
  prevent thundering herd on idle runners
- Tune HTTP client with MaxIdleConnsPerHost=10 and share a single
  http.Client between Ping and Runner service clients
- Add configurable options: log_report_interval, log_report_max_latency,
  log_report_batch_size, state_report_interval, fetch_interval_max
