CultNetWriteNotSentException names the pre-send boundary (connect, hello, no endpoint,
or a send port that proves nothing was written). Every other forwarding failure keeps
the session claim. ForUnownedSchema and the routing refusal no longer carry exception text.

CultNetWriteCompletion.SendAndAwaitResultAsync registers a refusal handler before
the send, then waits a result window (default 500 ms; CultMeshClientOptions.
SubmitResultWindow, CultNetSchemaWriteForwarderOptions.ResultWindow). A
cultnet.error.v0 inside it rejects with the new CultNetWriteRefusedException
(Code: write_not_authorized, message_invalid, ...) whatever its order against the
send or transport ack; a send returning no longer completes the write. The
forwarder's refusal now throws on the same path as an unreachable primary, so
CultNetDatabaseServer.TryForwardPutAsync/DeleteAsync no longer report a refused
forward as done. Raw send primitives (C# schema client/session, Python, Kotlin)
carry the doc line: fire-and-forget, an ack or a return is not admission, read the
result frame.
