docs: purge chain-of-thought leakage from prose

Delete design-session citations (decision/audit/plan ordinals, stack
positions), change narration, review choreography, and reviewer-addressed
justification from comments, JSDoc, docs, READMEs, Agent Notes, tests, and
generator templates; restate every affected fact as current-state contract
prose. Fix generated docs at their sources and regenerate the catalogs and
cordis-surface regions; re-paste type-equiv blocks; update every bilingual
counterpart and re-record the pairs. Record the citation rule in the
committed-artifact-citations Agent Note.

 `LlmService` normalizes failures from final adapter selection, synchronous dispatch, iterator construction, and iteration into the stream protocol's single terminal form: `finish { kind: 'error' | 'aborted', failure }`. A failure after partial deltas may leave content blocks open; consumers discard that incomplete output. Errors from `llm/stream` middleware, nested calls, adapter cleanup, and downstream consumers remain thrown because they are plugin or consumer failures rather than model-request outcomes. A prepared call exposes the immutable retry policy captured with its exact adapter registration; a route handled entirely by middleware has no serving policy.
 
-Interrogating an endpoint is configuration-time work over a *draft*, which is why it is keyed by settings namespace rather than by provider route: the provider a surface is adding does not exist yet, so there is no route to name. The request may still *name* a route it is editing, and an adapter that already describes that route should answer from its own knowledge — better metadata, no network call — which is why `baseURL` is optional and one of the two is required. The request otherwise carries the endpoint, the protocol, and a credential the harness uses for that one interrogation and never stores — nothing here reads or writes settings or credentials, and the reply is candidate metadata a surface may offer for adoption, never a registered catalog. `LlmDiscoveredModel` makes every field but `id` optional because most provider listings disclose an id and nothing else; a surface adopting one still owes the capacities its adapter requires. Duplicate and unusable ids are dropped, an unserved namespace fails with `NO_DISCOVERY`, and a request naming neither a route nor an endpoint fails with `INVALID_DISCOVERY`.

 Provider and model metadata is a discovery surface, not a routing whitelist. `registerAdapter()` still owns provider exclusivity and captures the adapter's retry policy for each route, while an adapter may accept model ids absent from `listModels()`; consumers must not reject a request because its model is unlisted. Returned selector metadata is detached and invalid or duplicate adapter entries fail with `INVALID_ADAPTER` or `INVALID_CATALOG`.

 `LlmService` 将最终适配器选择、同步 dispatch、iterator 构造与迭代中的失败规范化为流协议唯一的终止形式：`finish { kind: 'error' | 'aborted', failure }`。部分增量输出后发生失败时，内容块可能仍未闭合；消费方会丢弃这些不完整输出。`llm/stream` middleware、嵌套调用、适配器清理和下游消费方的错误仍会抛出，因为它们属于插件或消费方失败，而非模型请求结果。已准备调用会暴露随其确切适配器注册一同捕获的不可变重试策略；完全由 middleware 处理的路由没有服务策略。

 提供方与模型元数据是发现接口，不是路由白名单。`registerAdapter()` 仍拥有提供方排他性，并为每条路由捕获适配器的重试策略；适配器则可以接受 `listModels()` 中不存在的模型 id，消费方禁止因模型未列出而拒绝请求。返回的 selector 元数据与输入脱离，无效或重复适配器配置项会以 `INVALID_ADAPTER` 或 `INVALID_CATALOG` 失败。
