moq-rs's `Publisher::run` accepts `ControlType::Goaway = 5` as a
graceful-shutdown signal that asks the publisher to migrate to a
different relay node (`rs/moq-lite/src/lite/publisher.rs`). Our enum
only defined Session/Announce/Subscribe/Fetch/Probe; an inbound
Goaway bidi fell through `MoqLiteControlType.fromCode` as `null`,
hit the unknown-control branch in `handleInboundBidi`, and was FIN'd
silently — losing the relay's shutdown notification entirely.
Add `Goaway(5L)` to the enum and a dedicated arm in `handleInboundBidi`
that logs the event and FINs cleanly. We don't act on the migration
request today (no body decode, no preferred-relay failover); the
`connectReconnecting*` wrappers' transport-loss reconnect path
already recovers from the eventual hard disconnect, so all this arm
needs is to surface the relay's intent in logcat instead of
swallowing it. Wire body decoding is left as a follow-up.
