InMemoryCursorStore class final

A CursorStore that keeps the cursor in memory only.

The default when no store is injected. It makes the cursor survive reconnects within one process, which is what keeps a relay hiccup from losing events, but not a restart — for that the caller must supply a durable implementation.
