feat(codex-bridge): per-step check with Jev, blocked steps go to a fallback model

User decision (11 Oct 2026): every step of an added model is checked in the
bridge; Jev only passes or blocks; a blocked step is redone by
Uncensored-Uygulama and the next step goes back to the selected model.

The bridge buffers the step's answer, asks Jev four yes/no questions and
decides in code: blocked when the answer refuses or dodges the request, or
changes it with its own conditions without asking; passed when it reports a
concrete technical obstacle, asks the user a question, or has no text (tool
calls only). While buffering the client gets SSE comment lines. Jev unreachable
or fallback unavailable: the first answer is delivered. Codex's own models do
not reach the bridge and are not checked.

Also logs the shape of each forwarded request (not its content): the recurring
"upstream 400" turned out to be Codex's trailing configuration_update item.
