What

Implemented a two-stage select pattern inside ScanStream's onEvent callback in pkg/scan/scan.go.

Risk

When sending critical terminal events (such as EventLifecycleComplete) to eventChan while ctx.Done() is simultaneously ready, Go's pseudo-random select could silently choose to abort without sending the event. This causes consumer frontends to hang indefinitely waiting for the scan completion event.

Solution

Added a first-pass non-blocking select prioritizing the eventChan send over context cancellation checking. The fallback default block then enters the standard blocking select encompassing both the channel and ctx.Done(). This guarantees the terminal event gets enqueued successfully if the channel has capacity.
