What:
Added TestNoGoroutineLeakOnPrematureCancel to pkg/scan/engine_test.go and wrapped the channel send in pkg/ports/scanner.go with a select statement on ctx.Done(). Updated CHANGELOG.md and .jules/bolt.md.

Why:
To ensure that the asynchronous dispatcher in pkg/scan and the port scanner do not leak worker goroutines when the consumer prematurely stops reading from the event channel due to context cancellation. This validates the select statement blocking fix and ensures defensive channel sending.

Impact:
Prevents memory and goroutine exhaustion in long-running processes consuming ScanStream during frequent user-initiated aborts.

Measurement:
Confirmed via runtime.NumGoroutine() delta before and after the simulated early abort, successfully resulting in <= 3 diff.
