Adds the multi-server arbitration scenario from #62. The spec's rules — "must complete handshake first, prefer last-played server, send `another_server` on switch" — are unenforced today. Per the audit, only sendspin-cpp and sendspin-cli (via aiosendspin) implement them; six client SDKs collapse to "whichever connection happened first" and default to the wrong goodbye reason on switch. `multi-server-arbitration` is declared on the aiosendspin server only. Every client case fails fast until each adapter declares the capability based on the SDK's exposed surface.
