Qualify the display-only claim in the detailed documentation.

Line 338 correctly documents a routing exception. However, lines 718-719 still state without qualification that modelDisplayNames does not affect routing or upstream request construction. For a direct other/a-b request with a cold roster and a "a/b" key, src/router.ts now selects a/b as the native model ID. Add the exception to that paragraph and to the matching paragraphs at ja/reference/configuration/providers.md Line 502, ko/reference/configuration/providers.md Line 515, ru/reference/configuration/providers.md Line 596, and zh-cn/reference/configuration/providers.md Line 532. As per coding guidelines, “Update all directly affected pages when a user workflow changes.” (raw.githubusercontent.com)

@docs-site/src/content/docs/reference/configuration/providers.md at line 338:
Update the detailed documentation for modelDisplayNames to qualify the claim
that it never affects routing or upstream request construction: document that a
direct provider/model selector with no known, alias, or retained match may use a
matching encoded key as the native model ID. Apply the same clarification to the
corresponding Japanese, Korean, Russian, and Chinese documentation paragraphs.

| `contextWindow?` | `number` | Provider-wide context fallback when upstream metadata is absent; otherwise a cap that retains smaller live metadata. Registry defaults cannot override a lower configured limit; explicit `modelContextWindows` entries take priority. The Models dashboard exposes this separately from `providerContextCaps`. |
| `modelContextWindows?` | `Record<string, number>` | Per-model context fallbacks/caps. These override `contextWindow`: an unknown window uses the configured value, while smaller live metadata remains authoritative. |
| `inferContextWindow?` | `boolean` | Custom providers only, default off. `true` fills a missing window from bundled model-ID metadata ([details](#context-windows-on-custom-providers)); the value is an estimate, not verified relay capacity. |

Для каждого ID сохраняется только первое вхождение. |

Имена имеют приоритет над metadata каталога провайдера и не меняют аутентификацию, adapter, routing, billing или upstream-запросы. Исключение: если прямой селектор `provider/model` не совпадает ни с известным id, ни с alias, ни с `retainModels` (например, пока live-каталог ещё не загружен), ключ с совпадающей закодированной формой отправляется как нативный id. Карта содержит не более 2 000 записей, как и discovery. |
| `contextWindow?` | `number` | Значение контекста для всего провайдера, применяемое когда upstream не отдаёт metadata; при наличии metadata работает как cap и сохраняет более маленькое live-значение. Панель Models настраивает его отдельно от `providerContextCaps`. |
| `modelContextWindows?` | `Record<string, number>` | Значения и cap'ы контекста по отдельным моделям. Перекрывают `contextWindow`: если окно неизвестно, берётся заданное значение, а более маленькая live-metadata остаётся авторитетной. |
| `inferContextWindow?` | `boolean` | Только для пользовательских провайдеров, по умолчанию выключено. `true` заполняет отсутствующее окно из встроенных метаданных модели; это оценка, а не проверенная ёмкость посредника. |
