Long Li 22e1b8144a feat(gateway): expose routed Codex model catalogs
Codex model discovery expects a top-level models manifest, but Composite and other non-OpenAI groups either reached the OpenAI live-manifest handler or had no Codex-specific response at all. API key users also had no supported way to fetch that manifest and reference it from config.toml.

Generate minimal manifests from each group's effective model list while preserving the official OpenAI live path and the ordinary /models response. Add the Use Key flow for authenticated catalog download and model_catalog_json configuration without writing the API key into the downloaded file.

limingeandClaude Fable 5 13e773ef5e feat: Codex 客户端模型清单(manifest)透传接口
背景:Codex CLI / Codex App 会从 provider 的 GET {base_url}/models?client_version=...
(自定义 provider 模式)或 GET /backend-api/codex/models(chatgpt_base_url 模式)
刷新模型选单,期望 ChatGPT Codex manifest 格式({"models":[{slug,...}]})。
sub2api 此前只提供 OpenAI 兼容格式的 /v1/models,Codex 客户端解析失败后静默
回落到本地缓存,导致指向 sub2api 的 Codex 客户端模型选单永久冻结在切换
provider 当天的状态,新模型(如 gpt-5.6 系列)永远不会出现。

方案:新增 manifest 透传——用组内可调度 OAuth 账号的凭据向
chatgpt.com/backend-api/codex/models 实时转发请求,响应体与 ETag 原样透传。
不在网关侧解析或维护模型清单:manifest schema 随 Codex 客户端版本演进,
透传保证网关无需跟进 schema 变化,且返回的始终是账号真实的模型权限
(区别于静态 DefaultModels 的"理论列表")。

路由:
- GET /backend-api/codex/models(新增)
- GET /v1/models 带 client_version 查询参数且组平台为 openai 时分发到
  manifest 透传(client_version 是 Codex 客户端的天然指纹,普通 OpenAI
  客户端不携带);其余请求保持原有 OpenAI 格式行为不变。

上游失败时按 fast-fail 返回错误,不伪造列表;Codex 客户端自身会回落缓存。
