Enable openai_chat routing with explicit model catalogs across the major
Chinese/Asian providers (DeepSeek, Zhipu GLM, Kimi, MiniMax, Baidu Qianfan,
Bailian, StepFun, Volcengine Agent Plan, BytePlus, DouBaoSeed, ModelScope,
Longcat, BaiLing, Xiaomi MiMo, SiliconFlow, Novita AI, Nvidia, etc.). Each
preset declares its context window so the UI can size catalog rows when the
preset is picked.
Also lands two consistency fixes uncovered along the way:
- Include setCodexCatalogModels in resetCodexConfig's useCallback deps to
match the new third parameter it consumes.
- Realign TheRouter Codex test to the "custom" model_provider bucket
established by the recent third-party unification; the previous assertion
predated that refactor and had been failing on HEAD.
- Add Claude Desktop Official to the Claude Desktop preset list.
- Treat selected official presets as official mode in the form.
- Cover the official preset with a preset-order regression test.
Remove the category-based grouping logic from ProviderPresetSelector,
letting the array position in each preset config file be the single
source of truth for display order. Move partner presets (PatewayAI,
火山Agentplan, BytePlus, DouBaoSeed) right after Shengsuanyun across
all 6 config files so they appear earlier in the UI.
