feat(codex-bridge): ship the local Codex bridge with the IDE

Adds the IDE's models and combos to Codex's model list and keeps conversation
summaries readable across providers, so switching models in Codex no longer
drops the conversation. Standard-library Python, run on the agent venv.

+# AITURK IDE Codex bridge
+
+Local HTTP proxy that AITURK IDE's **Settings → Codex Bağlama** runs for OpenAI Codex
+(desktop or CLI) on the same computer. Standard-library Python only; it runs on the
+agent venv's interpreter and keeps running after the IDE window closes, because
+Codex depends on it while `openai_base_url` points here.
+
+- `bridge.py`: the proxy. Subscription models go to chatgpt.com unchanged; `ide/<id>`
+  models go to the AITURK gateway configured in the agent's `config.yaml`, with the
+  key read from the agent's `.env` on every catalog refresh (never written elsewhere).
+- `ide_catalog.py`: which IDE models and combos are added to Codex's model list and
+  how they are named (`provider/model`, combos by bare name).
+- `ozet_kopru.py`: conversation summaries are produced as plain text, so a summary made
+  by one provider stays readable after the user switches to another.
+- `gemini_context.py`, `resim_context.py`: request fixes for routed models.
+
+Run: `python bridge.py --home <data dir> --hermes-home <agent home>`. The IDE writes
+`<data dir>/bridge.json` and reads `GET /aiturk/codex-baglama/status`;
+`POST /aiturk/codex-baglama/stop` ends the process.
+
+Tests: `python -m unittest discover` in this directory.
