feat: add active meeting list shortcut

`append` always inserts at document end (equiv. `block_insert_after --block-id -1`),
but skill docs previously recommended it for the "skeleton + chapter-by-chapter fill"
pattern, causing all content to pile up after the last heading.

Changes:
- Remove `append` from skeleton workflow guidance in `lark-doc-create-workflow.md`
  and `lark-doc-create.md`; recommend `block_insert_after` with explicit `--block-id`
- Fix `block_move_after` required params: remove `--content` (not supported),
  only `--block-id` and `--src-block-ids` are valid
- Add bash language tag to code block for proper highlighting

 ### Structured errors in commands
 
-`RunE` functions must return `output.Errorf` / `output.ErrWithHint` — never bare `fmt.Errorf`. AI agents parse stderr as JSON; bare errors break this contract.
+Command-facing failures must be typed `errs.*` errors — never the legacy `output.Err*` helpers and never a final bare `fmt.Errorf`. AI agents parse the stderr envelope's `type` / `subtype` / `param` / `hint` fields to decide their next action; the full taxonomy lives in `errs/ERROR_CONTRACT.md`.
+
+Picking a constructor:
+
+| Failure | Constructor |
+|---------|-------------|
+| User flag/arg fails validation | `errs.NewValidationError(errs.SubtypeInvalidArgument, ...).WithParam("--flag")` |
+| Valid request, wrong system state | `errs.NewValidationError(errs.SubtypeFailedPrecondition, ...).WithHint(...)` |
+| Lark API returned `code != 0` | `runtime.CallAPITyped` (shortcuts) / `errclass.BuildAPIError` (raw responses) — never hand-build |
+| Network / transport failure | `errs.NewNetworkError(errs.SubtypeNetworkTransport, ...)` |
+| Local file I/O failure | `errs.NewInternalError(errs.SubtypeFileIO, ...)` — validate the path first (`validate.SafeInputPath` / `SafeOutputPath`) and use `vfs.*` |
+| Unclassified lower-layer error as final | `errs.NewInternalError(errs.SubtypeUnknown, ...).WithCause(err)` |
+| Lower layer already returned a typed error | pass it through unchanged — re-wrapping downgrades its classification |
+
+Signatures that are easy to guess wrong:
+
+- `runtime.CallAPITyped(method, url string, params map[string]interface{}, data interface{}) (map[string]interface{}, error)` — it performs the HTTP request itself and classifies `code != 0` into a typed error; just return the error it gives you.
+- Typed pass-through check: `if _, ok := errs.ProblemOf(err); ok { return err }` — `ProblemOf` returns `(*errs.Problem, bool)`, not a nilable pointer.
+- `.WithParam` exists only on `*errs.ValidationError`. `InternalError` / `NetworkError` have no param field — file or endpoint context goes in the message or `.WithHint(...)`.
+
+`forbidigo` + `lint/errscontract` reject the legacy `output.Err*` helpers, bare final `fmt.Errorf` / `errors.New`, and legacy envelope literals on migrated paths. Beyond what lint catches, three authoring conventions apply:
+
+- Preserve the underlying error with `.WithCause(err)` so `errors.Is` / `errors.Unwrap` keep working.
+- `param` names only the user input that actually failed. Recovery guidance goes in `.WithHint(...)`; machine-readable recovery fields (`missing_scopes`, `log_id`) carry server/system ground truth only — never caller-side guesses.
+- Error-path tests assert typed metadata via `errs.ProblemOf` (`category` / `subtype` / `param`) and cause preservation, not message substrings alone.

+|---|---|
+| 查待办/已办 | `tasks query`（`topic`：1待办 2已办 17未读 18已读）|

-**CRITICAL — 术语约束：用户日常表达中常说的“帮我约个日历”、“查一下今天的日历”等，其实际意图通常是针对 日程（Event） 的创建或查询，而非操作 日历（Calendar） 容器本身。请自动将口语化的“日历”意图映射为“日程”操作（如 `+create`, `+agenda`）。**
-**CRITICAL — 会议与日程的意图路由：**
-- **查询过去时间的会议**：如果用户明确查询过去时间的会议（如“昨天的会议”、“上周的会议”），**优先使用 [`../lark-vc/SKILL.md`](../lark-vc/SKILL.md) 搜索会议记录**。因为会议数据不仅包含从日程发起的视频会议，还包含即时会议，仅查询日程数据会导致结果不全。
-- **查询日历/日程或未来时间的会议**：如果用户明确表达的是“日历”、“日程”，或者涉及**未来时间**的安排，则属于本技能（lark-calendar）的业务域，请继续使用本技能处理。
-**CRITICAL — 任务类型分流：处理“预约/改约日程、添加/移除参会人、添加/更换会议室、调整时间”时，必须先判断用户是在“新建日程”还是“编辑已有日程”。**
-- **编辑已有日程的强信号**：用户明确提到某个已存在的日程锚点（如标题、时间段、`这个日程`、`这场会`）并表达修改动作（如“添加”“移除”“改到”“换会议室”“调整时间”）。这类请求默认走**编辑已有日程**，绝不能直接按新建处理。
-- **编辑已有日程的前置步骤**：一旦判定为编辑，MUST 先定位目标日程或具体实例的 `event_id`，再继续后续流程。若是重复性日程，MUST 先定位到对应实例的 `event_id`。
-- **新建日程**：只有当用户表达的是“新约一个会/创建一个日程/安排一次会议”等新增意图，且没有指向某个既有日程的修改动作时，才进入新建流程。
+开始前先读 [`../lark-shared/SKILL.md`](../lark-shared/SKILL.md)（认证、权限处理）。
 
-**CRITICAL — 验证与同步延迟：在涉及删除日程（delete）、修改日程（patch）或者涉及添加移除参与人/会议室之后，如果需要进行二次查询验证操作结果，MUST 等待至少 2 秒后再进行查询，以防止因数据同步延迟导致查不到最新数据。注意：不要向用户提及你等待了这 2 秒钟的事情。**
+**CRITICAL — 凡涉及预约日程/会议或查询/搜索会议室，第一步 MUST 读 [`references/lark-calendar-schedule-meeting.md`](references/lark-calendar-schedule-meeting.md)。禁止跳过此步直接调用 API 或 Shortcut！**
 
-**CRITICAL — 重复性日程的实例操作：目前已经完全具备对重复性日程的某个具体实例进行操作的能力（例如：编辑某个实例、删除某个实例、为某个实例添加/删除参与人、为某个实例添加/移除会议室）。只要在对应的操作中传递对应实例的 `event_id` 即可。因此，MUST 先定位到对应的那次实例的 `event_id`（可通过 `events search_event` 搜索日程，或 `+agenda` 查看对应时间范围的日程等相关查询获取），绝对禁止直接使用原重复性日程的 `event_id` 进行操作。**
+## 身份
 
-**时间与日期推断规范：**
-为确保准确性，在涉及时间推断时，请严格遵循以下规则：
-- **星期的定义**：周一是一周的第一天，周日是一周的最后一天。计算`下周一`等相对日期时，务必基于当前真实日期和星期基准进行推算，避免算错日期。
-- **一天的范围**：当用户提到`明天`、`今天`等泛指某一天时，时间范围应默认覆盖整天时间范围。**切勿**自行缩减查询范围，以免遗漏晚上的时间安排。
-- **历史时间约束**：不能预约已经完全过去的时间。唯一的例外情况是“跨越当前时间”的日程，即日程的开始时间在过去，但结束时间在未来。
+日程操作默认使用 `--as user`（查看和管理当前用户的日程）。`--as bot` 只能访问 bot 自己的（空）日历，会拿到空结果——不要用 bot 身份查用户日程。
 
-## 核心场景
+```bash
+# BAD — bot 身份查用户日程，返回空列表
+lark-cli calendar +agenda --as bot
 
-### 1. 预约新日程/会议、编辑已有日程、查询/搜索可用会议室

-## 核心概念
-
-- **日历（Calendar）**：日程的容器。每个用户有一个主日历（primary calendar），也可以创建或订阅共享日历。
-- **日程（Event）**：日历中的单个日程，包含起止时间、地点、标题、参与人等属性。支持单次日程和重复日程，遵循RFC5545 iCalendar国际标准。
-- ***全天日程（All-day Event）***: 只按日期占用、没有具体起止时刻的日程，结束日期是包含在日程时间内的。
-- **日程实例（Instance）**：日程的具体时间实例，本质是对日程的展开。普通日程和例外日程对应1个Instance，重复性日程对应N个Instance。在按时间段查询时，可通过实例视图将重复日程展开为独立的实例返回，以便在时间线上准确展示和管理。
-- **重复规则（Rrule/Recurrence Rule）**：定义重复性日程的重复规则，比如`FREQ=DAILY;UNTIL=20230307T155959Z;INTERVAL=14`表示每14天重复一次。
-- **例外日程（Exception）**：重复性日程中与原重复性日程不一致的日程。
-- **参会人（Attendee）**：日程的参与者，可以是用户、群、会议室资源、外部邮箱地址等。每个参与人有独立的RSVP状态。
-- **响应状态（RSVP）**：参与人对日程邀请的回复状态（接受/拒绝/待定）。
-- **忙闲时间（FreeBusy）**：查询用户在指定时间段的忙闲状态，用于会议时间协调。
-- **会议室（Room）**：“room”不是“房间”，是“会议室”。请在理解和处理意图时将“room”和“房间”准确映射为“会议室”及其相关操作。
-- **时间块（Time Slot / Time Block）**：指一个**具体且确定**的连续时间段（如 `14:00~15:00`）。在文档中，它与泛指的“时间范围/区间”（如“今天下午”、“下周”）有严格区别。在调用预定、查询可用会议室等确切操作时，必须基于确定的“时间块”而非模糊的“时间范围”。

+| 场景 | 前置要求 |
+|------|----------|
+| 预约日程/会议、查会议室 | 先读 [lark-calendar-schedule-meeting.md](references/lark-calendar-schedule-meeting.md) |
+| 编辑已有日程 | 先定位目标日程 `event_id`；若是重复性日程，必须定位到具体实例的 `event_id`（禁止使用原重复日程 ID） |
+| 删除/修改后验证 | 等待 2 秒再查询（API 最终一致性），不要告知用户你等待了 |
+| 调用任何 Shortcut | 先读其对应 reference 文档 |
+
+## 核心概念
+
+- **日程实例（Instance）**：重复性日程展开后的具体时间实例。操作重复日程的某次实例时，必须先定位该实例的 `event_id`，禁止使用原重复日程的 `event_id`。
+- **全天日程（All-day Event）**：只按日期占用、没有具体起止时刻的日程，结束日期是包含在日程时间内的。
+- **时间块 vs 时间范围**：时间块是具体确定的连续时间段（如 `14:00~15:00`），时间范围是泛指（如"今天下午"）。`+room-find` 必须基于确定时间块，不能基于模糊范围。
+- **会议室（Room）**："room"不是"房间"，是"会议室"。会议室是日程的一种参与人（resource attendee），不能脱离日程单独预定。
+
+## 术语映射
+
+用户日常说的"帮我约个日历""查一下今天的日历"，实际意图是针对**日程（Event）**的创建或查询，而非操作日历（Calendar）容器本身。自动将口语化的"日历"意图映射为"日程"操作。
+
+## 意图路由
+
+| 用户意图 | 路由到 |
+|----------|--------|
+| 查询过去的会议（"昨天的会议""上周的会"） | [`../lark-vc/SKILL.md`](../lark-vc/SKILL.md)（会议数据含即时会议，仅查日程会遗漏） |
+| 查询日历/日程或未来时间的会议 | 本 skill |
+| 预约/改约日程、添加/移除参会人、添加/更换会议室、调整时间 | 先判断新建 vs 编辑，再进入 [schedule-meeting 工作流](references/lark-calendar-schedule-meeting.md) |
+
+## 任务类型分流
+
+处理"预约/改约日程、添加/移除参会人、添加/更换会议室、调整时间"时，必须先判断新建 vs 编辑：
+
+- **编辑已有日程的强信号**：用户提到已存在的日程锚点（标题、时间段、`这个日程`、`这场会`）并表达修改动作（添加、移除、改到、换会议室、调整时间）。默认走编辑流，绝不能按新建处理。
+- **新建日程**：用户表达新增意图（"新约一个会""创建一个日程""安排一次会议"），且没有指向既有日程的修改动作。
+
+## 时间推断规范
+
+- **星期的定义**：周一是一周的第一天，周日是最后一天。计算"下周一"等相对日期时，基于当前真实日期推算。
+- **一天的范围**：用户提到"明天""今天"等泛指某天时，时间范围应覆盖整天，不要自行缩减。
+- **历史时间约束**：不能预约已经完全过去的时间。唯一例外是"跨越当前时间"的日程（开始在过去、结束在未来）。
+
+## 会议室规则
+
+- 凡是"预定/查询/搜索可用会议室"，都必须进入 [schedule-meeting 工作流](references/lark-calendar-schedule-meeting.md)。
+- `+room-find` 的时间输入必须是确定时间块，不能是时间区间搜索。
+- 用户仅要求"查会议室"但未提供明确时间时，必须先调用 `+suggestion` 获取可用时间块，再将时间块交给 `+room-find`。严禁猜测时间盲目调用。
+- 编辑已有日程时，"添加会议室"默认是增量语义，保留已有会议室；只有用户明确说"更换会议室""移除会议室"时才删除旧会议室。

+```bash
+lark-cli docs +fetch --api-version v2 --doc '<doc_token_or_url>' --detail with-ids
+```
+
+## 字段含义
+
+- `relation`：评论在文档内容中的结构化位置。`relation.relation` 是一个 JSON 字符串，需要再解析一次；其中 `positionInfo.blockID` 是最关键字段，用于匹配 `docs +fetch --detail with-ids` 返回的文档 block。
+- `relation.content_deleted`：评论引用的内容是否已被删除。为 `true` 时，不要假设还能在当前正文中找到原位置。
+- `parent_type`：评论所在的父级嵌入资源类型。常见值包括 `SHEET_BLOCK`、`BITABLE_BLOCK`、`WHITEBOARD_BLOCK`，表示评论落在文档内嵌电子表格、多维表格或画板内部。
+- `parent_token`：父级嵌入资源 token。对 sheet / bitable / whiteboard 内部评论，服务端可能无法给出内部单元格、记录或画板节点的文档 block 级 `relation`，但可以通过 `parent_type` + `parent_token` 定位到文档里的父级嵌入 block。
+
+## 准确度分级
+
+输出定位结论时，必须区分以下三类，不要把弱推断说成精确定位：
+
+| 等级 | 判定条件 | 输出口径 |
+|---|---|---|
+| `relation 精确` | `relation.relation` 中有 `positionInfo.blockID`，且能在 `docs +fetch --detail with-ids` 中匹配到同一 block | 可说“准确定位到 block” |
+| `父级资源精确，内部需下钻` | 只有父级嵌入资源的 `blockID` / `parent_type` / `parent_token`，或内部资源的 `positionInfo` 为空 | 可说“准确定位到嵌入资源；内部单元格/记录/节点需用对应 skill 下钻确认” |
+| `弱匹配/推断` | 只能依赖 `quote`、序号、当前展示顺序或文本搜索 | 必须标明“推断”，说明歧义来源和需要的补充信息 |
+
+## 返回示例
+
+普通 docx block 上的评论会返回 `relation`。注意 `relation.relation` 本身是字符串，需要再 JSON parse 一次：
+
+```json
+{
+  "comment_id": "7646774324967295982",
+  "quote": "code2",
+  "relation": {
+    "content_deleted": false,
+    "relation": "{\"22-doc_token_xxx\":{\"objType\":22,\"index\":2,\"objVersion\":10,\"positionInfo\":{\"blockID\":\"block_id_xxx\"}}}"
+  },
+  "parent_type": null,
+  "parent_token": null
+}
+```
+
+把 `relation.relation` 再解析后，取 `positionInfo.blockID`：
+
+```json
+{
+  "22-doc_token_xxx": {
+    "objType": 22,
+    "index": 2,
+    "objVersion": 10,
+    "positionInfo": {
+      "blockID": "block_id_xxx"
+    }
+  }
+}
+```
+
+然后在 `docs +fetch --detail with-ids` 的结果里查找同一个 block id，例如：
+
+```json
+{
+  "block_id": "block_id_xxx",
+  "block_type": "code",
+  "text": "code1\ncode2"
+}
+```
+
+嵌入 sheet / bitable / whiteboard 内部评论可能没有可用 `relation`，但会返回父级标记：
+
+```json
+{
+  "comment_id": "7646775036988148672",
+  "quote": "记录 2",
+  "relation": null,
+  "parent_type": "BITABLE_BLOCK",
+  "parent_token": "bitable_app_token_xxx_table_id_xxx"
+}
+```
+
+这种情况下，用 `parent_type` 判断目标是嵌入资源，再用 `parent_token` 匹配 `docs +fetch --detail with-ids` 中的 bitable / sheet block。定位粒度是文档里的父级嵌入 block，不是内部记录、字段或单元格。
+
+画板内部评论的返回形态类似：
+
+```json
+{
+  "comment_id": "7646775036988148673",
+  "quote": "画板节点文本",
+  "relation": null,
+  "parent_type": "WHITEBOARD_BLOCK",
+  "parent_token": "whiteboard_token_xxx"
+}
+```
+
+此时 `parent_token` 对应 `docs +fetch --detail with-ids` 结果中 `<whiteboard>` 的 `token` 属性，例如：
+
+```xml
+<whiteboard id="whiteboard_block_id_xxx" token="whiteboard_token_xxx"></whiteboard>
+```
+
+匹配到这个 `<whiteboard>` 后，`id` 就是文档正文里的父级画板 block id。定位粒度是文档里的画板 block；如果需要继续定位到画板内部具体节点，需要再用画板能力读取画板内部结构。
+
+## 定位流程
+
+1. 确认目标是 `file_type=docx`；只有 docx 文档支持通过 `need_relation` 查询评论位置。
+2. 用 `drive file.comments list` 或 `drive file.comments batch_query` 获取评论，并带 `need_relation=true`。
+3. 用 `docs +fetch --api-version v2 --detail with-ids` 获取文档内容。
+4. 对每条评论先看 `relation`：
+   - 如果存在 `relation.relation`，解析这个 JSON 字符串。
+   - 从解析结果里取 `positionInfo.blockID`。
+   - 在 `docs +fetch` 结果中查找相同 block id，这就是评论对应的文档 block。
+5. 如果没有可用 `relation`，但有 `parent_type` 和 `parent_token`：
+   - `SHEET_BLOCK`：定位到文档中的 sheet 嵌入 block；`parent_token` 通常包含 sheet token 和 sheet id，必要时取 `_` 前的 token 与文档 block 的嵌入资源 token 对比。
+   - `BITABLE_BLOCK`：定位到文档中的 bitable 嵌入 block；`parent_token` 通常包含 bitable app token 和 table id，必要时取 `_` 前的 token 与文档 block 的嵌入资源 token 对比。
+   - `WHITEBOARD_BLOCK`：定位到文档中的 whiteboard 嵌入 block；`parent_token` 对应 `docs +fetch --detail with-ids` 中 `<whiteboard>` 的 `token` 属性。
+   - 这种场景能定位到父级嵌入 block，但通常不能仅凭评论接口定位到嵌入资源内部的具体单元格、字段、记录或画板节点。
+6. 只有在 `relation`、`parent_type`、`parent_token` 都缺失时，才退回使用 `quote` 文本做弱匹配；`quote` 是评论接口返回的引用文本字段。弱匹配不能区分多处相同文本。
+
+## 嵌入资源内部定位
+
+### Sheet 内部评论
+
+- `parent_token` 常见格式是 `<spreadsheet_token>_<sheet_id>`；也可能在 `relation.relation` 中看到 `subToken` 为 `3-<spreadsheet_token>`。
+- 评论接口通常只把 `positionInfo.blockID` 指到文档里的 `<sheet>` block，内部 sheet 的 `positionInfo` 可能为空。
+- 如果 `quote` 是 `C3`、`A1` 这类单元格坐标，可拆出 `spreadsheet_token` / `sheet_id` 后用 `lark-sheets` 读取该单元格确认：
+
+```bash
+lark-cli sheets +read \
+  --spreadsheet-token '<spreadsheet_token>' \
+  --sheet-id '<sheet_id>' \
+  --range '<cell>'
+```
+
+- 准确度口径：父级 sheet block 可由 relation/parent token 精确定位；单元格坐标若只来自 `quote`，应说明“单元格来自 quote，已通过 sheets 读取验证”，不要说它来自 `positionInfo`。
+
+### Bitable / Base 内部评论
+
+- `parent_token` 常见格式是 `<base_token>_<table_id>`，其中 `table_id` 通常以 `tbl` 开头。解析时优先按最后一个 `_tbl` 边界拆分，避免 base token 内出现 `_` 时误拆。
+- 评论接口可能只返回 `parent_type=BITABLE_BLOCK` 和 `parent_token`，没有 `relation`；即使有 relation，也通常只足够定位到文档里的 `<bitable>` block。
+- 下钻读取时切到 `lark-base`，最少确认表、字段、记录：
+
+```bash
+lark-cli base +table-list --base-token '<base_token>'
+lark-cli base +field-list --base-token '<base_token>' --table-id '<table_id>'
+lark-cli base +record-list --base-token '<base_token>' --table-id '<table_id>' --limit 200 --format json
+```
+
+- 如果 `quote` 是某个稳定业务值，优先用字段/记录数据做精确匹配；如果 `quote` 只是“第 N 条”“第 N 行”这类 UI 序号，只能基于当前记录顺序推断对应记录，必须输出为“推断”，并说明评论接口没有返回 `record_id` / `field_id`。
+- 如果 `record-list` 返回 `has_more=true`，不要基于第一页下全局结论；继续分页或说明只能覆盖已读取范围。
+- 需要写入时，如果评论没有字段信息，不要自行猜字段；除非用户给出默认规则，否则请求用户确认字段，或明确说明将使用哪个字段作为默认。
+
+### Whiteboard 内部评论
+
+- `parent_token` 对应文档 XML 中 `<whiteboard token="...">`；先用它匹配文档里的 whiteboard block。
+- 若要定位画板内部节点，切到 `lark-whiteboard` 读取 raw 节点结构：
+
+```bash
+lark-cli whiteboard +query \
+  --whiteboard-token '<whiteboard_token>' \
+  --output_as raw
+```
+
+- 如果 raw 节点中存在唯一匹配 `quote` 的文本节点，可定位到该节点；如果有多个相同文本节点，仍然是弱匹配，需要结合位置、样式、用户描述或人工确认。
+- 修改画板节点前，先说明匹配到的节点 id 和文本；复杂画板不要只凭 `quote` 批量替换全部同名节点。
+
+## 使用原则
+
+- Review 文档时，不要只依赖 `quote` 文本定位评论；多处相同文本会产生歧义。
+- 能拿到 `relation.positionInfo.blockID` 时，以 block id 为准，再用 block 内容理解上下文。
+- 对嵌入 sheet / bitable / whiteboard 内的评论，以父级嵌入 block 作为文档正文定位点；如需继续定位到表格单元格、多维表格记录或画板内部节点，需要再调用对应 sheet / bitable / whiteboard 能力读取内部数据。

+
+在会列表来自 admin meeting_list（Ongoing）数据源。它匹配「IM 聊天后定位用户当前在哪些会」这类场景，但不保证毫秒级实时；刚入会/刚离会可能有秒级延迟。
+
+### 2. UAT 与 TAT 身份语义不同
+
+- UAT 返回的是**用户自己**的在会列表，按操作者身份天然鉴权，无需管理员权限。
+- TAT 在用户在会列表基础上**额外过滤**「bot 是否也在这场会中」，因此结果是用户与 bot 的**交集**。若 bot 未入任何会，TAT 通常返回空列表。
+
+### 3. 返回语义：无 / 单 / 多
+
+- **无**：`meetings` 为空数组——用户当前不在任何进行中会议（TAT 下为无共同在会）。
+- **单**：返回单条，可直接用其 `meeting_id`。
+- **多**：返回全部，由调用方提示用户选择。
