- Stream[T]: Send(v T) type-safe; message type recovered from the
instantiated Send signature (reflect has no type-args API)
- method signatures reduced to (error), (T, error), (*Stream[T], error);
the (T, *Stream, error) first-message form is gone — send it via Send
- return T and stream message T now run checkType at bind time
(Stream[any] remains the explicit untyped escape hatch)
- generated clients: TS onMessage: (data: T); Go <-chan T
- fix vacuous panic assertions (fmt.Sprint(nil) -> "<nil>") in
hardening/route test catch helpers
