Only perform the "Try stopping a cancelled server" on manual cancel

Before, we had this issue:

1: Terminal 1 - `kobweb run`, wait for server to start
2: Terminal 2 - `kobweb run`, say "yes" that you'd like to stop the running server
3: Terminal 1 - Detects its server got cancelled. Looks for an active server and tries to shut it down.
4: Terminal 2 - Detects its server got cancelled.

After this change, the third step will not follow up on the cancellation
event; not all cancel types are created equal. We only want to respond to the
user's direct action here.
