Critical fixes to prevent goroutine leaks during application shutdown: 1. Sync Queue Processor: - Changed StartCleanupTask() to return context.CancelFunc - Modified to accept and watch cancellable context - Added queue context/cancel to Handler struct - Created StartBackgroundTasks() method for main handler instance - Cancel queue processor during shutdown in StopScheduler() 2. Connection Manager: - Modified StartCleanupTask() to use cancellable context - Returns cancel function that can be called during shutdown - Goroutine now properly exits when context is cancelled 3. Handler Lifecycle: - Added StartBackgroundTasks() to Handler - Only main handler instance starts background goroutines - Temporary handler instances (library/sync routes) don't start tasks - StopScheduler() now properly shuts down all background goroutines 4. Router Integration: - Updated SetupRoutes to accept queueProcessor parameter - Main scanner handler starts background tasks after creation - Library and sync route handlers don't start duplicate tasks Impact: - Fixes 2 major goroutine leaks (queue processor + connection cleanup) - Application now properly shuts down all goroutines on exit - No more resource leaks from long-running goroutines - Test added to detect future goroutine regressions Test: TestGoroutineCleanup verifies background services can be stopped.
