"""AITURK IDE Codex bridge.

A small local HTTP proxy between OpenAI Codex (desktop or CLI) and its backend.
AITURK IDE's "Codex Baglama" setting points Codex's `openai_base_url` at it.

- POST .../responses  -> by model slug:
      * subscription models (no mapping) -> chatgpt.com, unchanged
      * "ide/<id>" models                -> the AITURK gateway the IDE itself uses
- GET  .../models     -> the IDE's models and combos are added to Codex's own list
- everything else     -> chatgpt.com, unchanged (voice, remote, auth)
- Conversation summaries (compaction) are produced as plain text so that every
  provider can read them when the user switches models (ozet_kopru.py).

Data directory (bridge.json, log/): --home <dir> or AITURK_CODEX_BRIDGE_HOME,
otherwise the script's own directory. Agent home: --hermes-home or HERMES_HOME.
Local control: GET /aiturk/codex-baglama/status, POST /aiturk/codex-baglama/stop.
