Commit Message

feat(server): add Server::subscribe() and demote state_rx to pub(crate) (#317)

`state_rx` was the only `pub` field among the eight on `Server`; the other
seven are `pub(crate)`. Exposing the `watch::Receiver` as a bare public field
pinned the serving-state observation API to a concrete field type — a future
newtype around `ServingState`, or any change to the receiver's type, would be
a breaking change to a public field rather than to a method.

Add `pub fn subscribe(&self) -> watch::Receiver<ServingState>` as the stable
observation API and demote `state_rx` to `pub(crate)`. Embedders that switch
to `subscribe()` are insulated from future representation changes.

Migrate every out-of-crate consumer (examples, integration tests, and the
tsoracle-tests crate) from `state_rx.clone()` to `subscribe()`, and dogfood
the method from the in-crate test support helpers. The in-crate service hot
path keeps its direct `state_rx.borrow()` access.

Closes #246
