feat(codex-bridge): decision-model stages, Dify rules and beta.39

Owner request, 14 October 2026: use the decision model (Jev / Celeris) at
several stages, let Dify supply the rules, code it without new bugs.
Every new stage is switched on in Settings > Kademeli Gecis and starts
disabled, so the upgrade changes no behaviour by itself.

- Settings schema 2 (Python and TypeScript validate the same rules); a
  schema 1 file is filled from the defaults. Default chain is now
  Katman-1 -> Katman-2 -> Katman-3 with Katman-3, Chat-Model and
  bekci-sesli-bekci always passing (owner decision of the same day).
- watchModels: the Bekci correction channel follows a settings list
  instead of the hard-coded Sesli-Hizli-Zeki.
- prefilter: a predicted refusal starts the step at the chosen layer.
- autoRoute: virtual "Otomatik" model; one decision per user turn picks
  the combo, tool steps of the same turn keep it.
- finishCheck: an answer that stops early goes back to the same model once.
- A layer whose window cannot hold the request is skipped.
- policy: stage rules from a Dify workflow (karar_politikasi.py), fetched
  in the background, validated, last good copy kept; turns never wait.
- karar_sor.py: verifierCheck for the dynamic-workflow acceptance step.
- Bridge version 19, IDE 1.0.0-beta.39.

Tests: 299 bridge tests, 36 electron tests; live run on a side bridge
(port 8797) with Celeris and the AITURK gateway for every stage.
