将 v1 schema 中 `providers.llm` 从 Ark 专用结构推广为通用 `CredentialsProviderLLMEntry`（containing displayName / temperature / extraHeaders）， 为 OpenAI / DeepSeek / DashScope / Moonshot 等多 LLM provider 共用一套字段。 旧 `CredentialsProviderLLMArk` 保留为 typealias，已迁移过的 v1 文件无需再次迁移即可继续解码。 新增公开 API： - `CredentialsVault.activeLLMProviderId` getter/setter - `CredentialsVault.configuredLLMProviderIds` - `CredentialsVault.llmProviderConfig(for:)` - `CredentialsVault.setLLMProviderConfig(_:)` - `CredentialsVault.removeLLMProvider(_:)`，禁删 active provider `OpenLessCore` 新增 `LLMProviderRegistry`，集中维护 5 家 OpenAI 兼容供应商 预设（baseURL / model / 帮助文案 / docs URL），UI 与 vault 兜底逻辑共用。 `PolishOutputCleaner` 从 DoubaoPolishClient 内部提升为独立 public 类型， 让 `OpenAICompatibleLLMProvider` 输出统一过 boilerplate / markdown 栅栏清理。 DoubaoPolishClient.swift 已无调用方，整个文件删除。 Tests: - LLMProviderRegistryTests：5 家预设健康检查 + 唯一性 / URL 合法性 - CredentialsVaultMultiProviderTests：active 默认 / 增删 / 往返 / 老 `ark.*` 账号 key 路由到 active provider
