feat(codex-link): AITURK work routing setting and beta.40

- Default routing rule (user decision, 15 Oct 2026): repeating/scheduled work goes to the AITURK IDE bot as a cron job; coding stays in Codex (itself or its subagents); 'Codex' or 'sen yap' keeps everything in Codex.
- Settings > Codex Bağlama: choice (recommended / send large work / never / custom text) with a text box and restore-default; written to bridge.json aiturk_hat.
- Bridge re-reads aiturk_hat when bridge.json changes: no restart. IDE apply keeps aiturk_hat instead of wiping it.
- Bridge version 20, IDE 1.0.0-beta.40. Jev untouched.
