Oracle re-review nit on PR #27: cite Apple's App Sandbox semantics
explicitly. The macOS sandbox classifies any UDP bind() against a
local port as a 'server' operation (covered by network.server),
even when the socket is only used to sendto() a remote peer. This
is the bind()-then-sendto() pattern tokio's UdpSocket uses
internally for tsclientlib's outbound voice traffic. Correct the
sandbox log line to the actual deny string ('Sandbox: ... deny(1)
network-bind') and reference Apple's entitlement reference wording.
