* Add Codex OAuth FAST mode toggle
* fix(codex-oauth): default FAST mode to off to avoid surprise quota burn
service_tier="priority" consumes ChatGPT subscription quota at a higher
rate. Users must now opt in explicitly rather than inherit FAST mode
silently when this feature ships.

- Trim Auth Center section descriptions to focus on user intent
- Remove duplicate outer heading on the auth settings tab
- Swap Sparkles glyph for CodexIcon on the ChatGPT card
- Generalize codexOauth.authStatus to a neutral "Auth status"
- Register settings.authCenter.* keys across zh/en/ja locales
Adds a new managed OAuth provider that lets Claude Code route requests
through a user's ChatGPT Plus/Pro subscription via the chatgpt.com
backend-api/codex endpoint.
- CodexOAuthManager: OpenAI Device Code flow with multi-account support,
JWT-based account identification, and automatic access_token refresh.
- Reuses the generic managed-auth command surface (auth_start_login,
auth_poll_for_account, etc.) via provider dispatch in commands/auth.rs.
- ClaudeAdapter detects codex_oauth providers, forces the base URL to
the ChatGPT backend, pins api_format to openai_responses, and emits
Authorization + originator headers; the forwarder injects the dynamic
access_token and ChatGPT-Account-Id per request.
- transform_responses gains an is_codex_oauth path that aligns the body
with OpenAI's codex-rs ResponsesApiRequest contract: sets store:false,
appends reasoning.encrypted_content to include, strips max_output_tokens
/ temperature / top_p, injects default instructions/tools/parallel_tool_calls,
and forces stream:true. Covered by 9 new unit tests plus regression
guards for the non-Codex path.
- Stream check reuses the same transform flag so detection matches the
production request shape.
- Frontend adds CodexOAuthSection + useCodexOauth hook, integrates it
into ClaudeFormFields / ProviderForm / AuthCenterPanel, ships a new
"Codex (ChatGPT Plus/Pro)" preset, and adds zh/en/ja i18n strings.
