docs: telemetry subsystem page and Chinese counterparts for the nine new pages

telemetry.md joins the eight pages after the OTel telemetry seam landed
on master (ctx.telemetry + telemetry/record were the one service and
event scope still without a page). All nine pages gain zh counterparts
translated whole-document per dsh-translate-docs; the eleven touched
pairs (nine new + core + the subsystems-catalog note) are recorded;
TelemetryRecord moves from TYPE_LINK_EXEMPTIONS to LINK_MAP and the
catalogs are regenerated.

+# 工作区
+
+[English](workspace.md) | 中文
+
+工作区（workspace）是用户工作目录的持久记录：一个建立在规范路径之上的稳定 id、一个显示标题，以及归属于它的会话的有序账本。该子系统是单个包（package）（[dsh-workspace](../../packages/workspace/workspace)，`ctx.workspace`）——一项宿主侧可选能力，不属于 agent loop（智能体循环）主干，并且对模型不可见（没有工具、没有提示词文本、没有会话事件）。它通过[存储领域数据形式](storage.md)存储自己的记录，并对照 [`SessionHeader.cwd`](persistence.md#sessionheader--metadata-beside-the-log) 校验会话成员资格，因此 `storageDomain` 与 `sessionPersistence` 是必需的启动依赖：持久化这一侧不可用时插件保持 pending，而不会被误认为历史为空。设计记录：[领域 KV 存储 Agent Note（agent 决策记录）](../../.agents/notes/proposed/architecture/2026-07-24-domain-kv-storage-and-workspace.md)；引导与 GUI 顺序：[Workspace UI 产品流程 Agent Note](../../.agents/notes/implemented/feature/2026-07-25-workspace-ui-product-flow.md)。

+
+## 标识
+
+```ts type-equiv
+/**
+ * Identifies one workspace record. A generated uuid, never the path: path
+ * normalization rewrites paths, and a reference anchor must stay stable.
+ */
+type WorkspaceId = Branded<'WorkspaceId'>
+```
+
+`WorkspaceId` 是[品牌化 id](core.md#branded-ids)。路径标识与之分离：`realpathNormalize`（`fs.realpath`；尾部斜杠、`..` 与符号链接全部解析）是唯一的一套唯一性规范——工作区路径以规范化形式存储，唯一性即规范路径的字符串相等（指向已被拥有目录的符号链接会与之冲突），attach 时的会话 cwd 检查也走同一套规范。
+
+## 工作区实体
+
+消费方只看到 `Workspace` 接口；实现保持包内私有。
+
+```ts type-equiv
+/**
+ * One workspace: a stable id over an existing directory, a display title, and
+ * an ordered candidate account of sessions. Membership requires both an id in
+ * that account and a session header whose canonical cwd equals the workspace
+ * path. Consumers only see this interface; the implementation stays private.
+ */
+interface Workspace {
+  /** Stable record id (generated uuid). */
+  readonly id: WorkspaceId
+
+  /**
+   * Canonical directory path: the `fs.realpath` of the path given at create
+   * time (trailing slashes, `..`, and symlinks all resolved). Never rewritten
+   * afterwards, even when the directory disappears (see {@link status}).
+   */
+  readonly path: string
+
+  /** Display title. Defaults to `basename(path)` at create; duplicates are allowed. */
+  readonly title: string
+
+  /** ISO-8601 creation instant, stamped at create and never rewritten. */
+  readonly createdAt: string
+
+  /** ISO-8601 instant of the last durable mutation (create counts as one). */
+  readonly updatedAt: string
+
+  /**
+   * Header-validated sessions in manually owned order: a new session is
+   * prepended at attach, explicit reordering goes through
+   * `insertSessionBefore`, and activity never reorders. The durable candidate
+   * account is filtered synchronously: missing headers, invalid cwd values,

+  /**

+   * resolves without writing (decided on the domain write chain).
+   * @param sessionId - The accounted session to move.

+  insertSessionBefore(sessionId: SessionId, beforeSessionId?: SessionId): Promise<void>
+
+  /**
+   * Remove a session from this workspace's account. Idempotent: an id not on

+  detachSession(sessionId: SessionId): Promise<void>
+

+
+所有权的真源是记录中有序的 `sessionIds`，绝不从会话 cwd 派生——但成员资格要求两者同时成立：账本上有其 id，且 header 的规范 cwd 等于工作区路径，因此一个会话在结构上至多属于一个工作区。失败的写入会拒绝（`insertSessionBefore` 的账本错误以 `WorkspaceMoveInvalidError` 拒绝，存储失败以普通错误拒绝）；每次被接受的变更都盖上 `updatedAt` 时间戳，并持久修剪不再通过成员资格检查的候选项。
+
+## 注册表：`ctx.workspace`
+
+`WorkspaceRegistry`（[签名](../cordis-catalog/services.md#ctxworkspace--workspaceregistry)）拥有注册与解析。`create(path, title?)` 规范化路径，拒绝不存在的路径（原样抛出 `ENOENT`）或非目录；当规范路径已被拥有时原样返回既有实体；否则创建一条标题为 `title ?? basename(path)` 的记录并前插到持久的注册表顺序中——新记录不得与既有显示标题重复（`WorkspaceNameConflictError`）。`get(id)` 与有序的 `list()` 是同步缓存读取；`resolveByPath(path)` 应用同一套 realpath 规范但不创建。`delete(id)` 只移除注册记录、顺序条目和会话账本——目录、用户文件、实时会话和已持久化日志一概不动，因此这些会话变为 Ungrouped（[决策](../../.agents/notes/implemented/feature/2026-07-27-workspace-registration-deletion.md)）；未知 id 返回 `false`。create 与 delete 会在其两次写入（记录 + 顺序）可能分叉之前先持久写入一个待定变更标记；启动时恰好补完被标记的那次变更，而没有标记的顺序/表不一致则作为损坏大声失败。
+
+会话的 cwd 在创建时由创建者赋予，而不是由本注册表赋予——API 网关从所选工作区的 `path` 解析新会话的 cwd（回退到显式或默认 cwd），先创建会话使 cwd 落入其不可变的 [`SessionHeader`](persistence.md#sessionheader--metadata-beside-the-log)，再调用 `attachSession`，后者会把已存储的 header cwd 与工作区路径重新校验一遍。首次启动时，注册表仅凭已持久化的 header（`id`、`cwd`、`createdAt`——绝不读事件正文）引导历史：把规范 cwd 有效的会话按目录分组为工作区，最新的排在最前；「已初始化」标记最后写入，因此被中断的引导可以安全续跑，而没有 cwd 的历史遗留会话保持 Ungrouped。
+
+## 消费方
+
+[dsh-host-apiproxy](../../packages/host/apiproxy) 是产品消费方：它经 `ctx.workspace` 向 GUI 客户端提供工作区的 CRUD，并执行上文「先建会话再 attach」的流程。[dsh-workspace-context](../../packages/context/workspace-context) 尽管名字如此，却**不是**消费方：它在 agent 自己的 cwd 下发现 AGENTS.md 风格的指令文件，从不触碰 `ctx.workspace`——两者共用的这个词指的是用户的工作目录，而非本注册表的实体。
