Modernize executable tutorials

1. Adopt quorum queues for tutorials 1, 2, (partially) 6
   for visibility and as a better defaults; other tutorials
   inherently can use exclusive queues
2. Improve some tutorial code, bump some clients
3. Add some instructions for background machine execution
   because that's not how the tutorials are generally
   written to be run (they are for interactive use by humans)

+## `Console.ReadLine` in non-TTY environments
+
+Consumer programs (Receive, Worker, ReceiveLogs, ReceiveLogsDirect, ReceiveLogsTopic,
+RPCServer) use `Console.ReadLine` to block until the user presses `[Enter]`.
+
+When standard input is not connected to a TTY, `ReadLine()` returns `null` immediately and the process
+exits before receiving any deliveries.
+
+Keep stdin open in automated or background contexts by piping from a blocking process:
+
+```sh
+(while true; do sleep 20; done) | dotnet run --project Receive &
+(while true; do sleep 20; done) | dotnet run --project ReceiveLogs &
+```
+
+The `Console.ReadLine()` and the "Press [enter] to
+exit." must never be deleted as a workaround: they exist for interactive use.
