Performance — Startup & Exit Hang Fixed

Docker Module

  • Parallel stats collection: container stats now fetched concurrently (5 goroutines max) instead of sequentially
  • Timeout reduced: 15s → 5s global, 3s per-request with context.WithTimeout
  • HTTP client reused across ticks (was creating new client + transport every 3s)
  • Removed dockerInspect() calls (RestartCount was reading wrong JSON path, always returned 0)

Proper Cleanup Chain

Engine.Close() → Registry.CloseAll() → Manager.Close() → module Close() methods → CloseIdleConnections()

No more lingering HTTP connections on exit.
