feat(sheets): add chart data update shortcut

Reads are capped by max_chars (default 500000; the backend tool also truncates
at ~50000 when unset). Add --output-path to +cells-get / +csv-get / +table-get:
when set, the result is written to a cwd-relative path as JSON and the char cap
is lifted to unbounded, so a large sheet lands on disk in full instead of being
clipped for stdout.

+table-get previously never sent max_chars, so it silently dropped rows past the
backend ~50000 default with no signal. It now takes --max-chars (default 500000,
sent explicitly) and surfaces truncated / truncation_warning when the read is
clipped, steering callers to --output-path for a lossless full read.

 ## 飞书表格编辑准则（动手前必守，所有编辑类任务一律生效）
 
-下列准则横切所有飞书表格任务，**动手前先过一遍**——即使你是被索引直接路由进某个工具参考也一律生效。每条只给一句话纲要，展开与边界见括注的 reference。
+下列准则横切所有任务，**动手前先过一遍**——被索引直接路由进某个工具参考也一律生效；展开与边界见括注的 reference。
 
 1. **最小改动**：除任务要改的单元格 / 列外，原表其它单元格、行列结构、Sheet 名、合并区、格式 1:1 保持；中间结果放原数据右侧或新建空白 Sheet，**禁止删 / 改名 / 隐藏 / 移动已存在 Sheet**；改写类任务精确圈定行列，不该转的原值 1:1 保留。
 2. **真实写回 + 回读校验**：交付必须是对在线表格的真实写入，写完用 `+csv-get` / `+cells-get` / `+<对象>-list` 回读确认实际生效——**写操作返回 `ok` 只代表请求被接受、不代表结果符合预期**；写公式后查错误码、筛选 / 排序后核对前几行、删除 / 清空后确认已空。禁止只在文本里声称"已完成"。
 3. **读全再写**：批量填充 / 补齐 / 修正类任务先确认真实数据末行再写，只探前 N 行会漏写表尾（确定末行流程见 `lark-sheets-read-data`）。
-4. **公式优先于硬编码**：能用公式表达的计算（总计 / 占比 / 增长率 / 提取 / 查找）一律写公式而非静态值；**凡可由表内其它单元格推导的派生值默认就用公式，即使用户没说"联动 / 自动更新"**；写任何飞书公式前先读 `lark-sheets-formula-translation`，而且**只要公式真实写入表格，收尾默认就要继续跑 `lark-sheets-formula-verify` 的 `+formula-verify`，直到 `status='success'`**。

 5. **续写 / 扩展继承样式**：续写、补齐、复制区块、新增行列时禁止只读值只写值，必须连带 `cell_styles` + `border_styles` + 合并 + 行高一起继承（清单见 `lark-sheets-write-cells`，四边框最易漏）。
-6. **多步写入合并 `+batch-update`**：多个连续写入、或同一工具对多区域重复调用，合并为单次原子 `+batch-update`（语义见 `lark-sheets-batch-update`）。
+6. **多步写入合并 `+batch-update`**：多个连续写入、或同一工具对多区域重复调用，合并为单次原子 `+batch-update`（high-risk-write，**调用必带 `--yes`**；语义见 `lark-sheets-batch-update`）。
 7. **分组汇总用透视表**："按 X 统计 Y / 分组汇总 / 各类数量金额"用 `+pivot-{create|update|delete}`，禁止用 SUMIF / 本地脚本拼一张假透视表。
 8. **拆成可验证 checklist**：落地前把指令拆成所有"独立可验证子要点"，逐点 `assert` 全过才交付（多维排序每维一点、多目标每目标一点、范围类核起 / 末 / 边界）；只做第一个要点属违规。
 9. **全量处理前置断言条数**：翻译 / 打标 / 批量公式落地等逐条任务，先把预期条数硬编码再 `assert actual == expected`，禁止输出"已完成前 N 条，剩余继续"的半成品。

 ### 公共 flag（定位资源）
 
 **公共四件套** = `--url` / `--spreadsheet-token` / `--sheet-id` / `--sheet-name`，分成两组 XOR，**每组都必须给且只能给一个**（XOR = 二选一必填，不是"可选"）：
 
-1. **spreadsheet 定位（必填）**：`--url` 与 `--spreadsheet-token` 二选一，**必须给其中之一**。两个都不给 → 校验报错 `specify at least one of --url or --spreadsheet-token`；两个都给 → 互斥冲突。
-   - **`--url` 解析 `/sheets/`、`/spreadsheets/` 与 `/wiki/` 三种链接**（从路径里抽出 token；也可以直接把裸 token 传给 `--spreadsheet-token`）。其它形态的链接不会被解析成表格 token。
-   - **`/wiki/` 知识库链接可直接传 `--url`**：会自动定位到链接背后的电子表格；若该链接背后不是电子表格（而是文档 / 多维表格等），则报错。
-   - **例外**：`+workbook-create`（新建表 + 可选写入数据）与 `+workbook-import`（把本地文件导入为新表）都产出一张**还不存在**的表格，**不接受任何 spreadsheet / sheet 定位 flag**——`+workbook-create` 只有 `--title` / `--folder-token` / `--values` / `--styles` / `--sheets`，`+workbook-import` 只有 `--file`（必填）/ `--folder-token` / `--name`。
-2. **sheet 定位（公共四件套 shortcut 必填）**：`--sheet-id` 与 `--sheet-name` 二选一，**必须给其中之一**。两个都不给 → 校验报错 `specify at least one of --sheet-id or --sheet-name`。
-   - ⚠️ **不确定 sheet 名时禁止直接猜 `Sheet1`**：除非用户对话明确说出 sheet 名 / id，或上下文（之前的工具调用 / URL 锚点 `?sheet=xxx`）已经出现过具体值，否则**第一步先调 `+workbook-info --url "..."`**（或 `--spreadsheet-token`）拿 `sheets[].sheet_id` / `sheets[].title` 列表再选。中文环境下子表常叫"数据" / "Sheet"（无数字）/ "工作表 1" / 业务名，猜 `Sheet1` 大概率撞 `sheet not found`，比先查多耗一次失败调用 + 重试。
-   - ⚠️ **`--range` 里的 `Sheet1!` 前缀不能替代 sheet 定位**：即使写了 `--range 'Sheet1!A1:B2'`，仍**必须**额外传 `--sheet-id` 或 `--sheet-name`，否则照样报上面的错。
-   - ⚠️ **A1 reference 含 `!`**（`--source` / `--range` / `--ranges`）**：整段用单引号包裹**，如 `--range 'Sheet1!A1:B2'`——单引号能挡住 bash 的 history expansion（`!` 被拦成 `event not found`；双引号挡不住；别改用 `set +H`，原因见下方「复合 JSON / 大入参」）。sheet 名含特殊字符（`-` / 空格 / 非 ASCII）需在内部按 A1 标准再包一层单引号时，用 `'\''` 转义保持外层单引号，如 `--source ''\''Sales-2025'\''!A1:D100'`。
-   - **例外**：徽章标为 `_公共：URL/token（无 sheet 定位）…_` 的 shortcut（如 `+workbook-info` / `+workbook-export` / `+batch-update` / `+dropdown-update|delete` / `+cells-batch-set-style` / `+cells-batch-clear` / `+sheet-create`）**不接受也不需要** sheet 定位，只给一组 spreadsheet 定位即可。`+pivot-create` 用 `--target-sheet-id` / `--target-sheet-name`（XOR，可都不传，落点细节见 `lark-sheets-pivot-table`）。

+2. **sheet 定位（公共四件套 shortcut 必填）**：`--sheet-id` 与 `--sheet-name` 二选一。
+   - ⚠️ **不确定 sheet 名时禁止猜 `Sheet1`**：除非对话或上下文已出现具体值，第一步先 `+workbook-info` 拿 `sheets[].sheet_id/title` 再选——中文表的子表常叫"数据"/"工作表 1"/业务名，猜名大概率撞 `sheet not found`。
+   - ⚠️ **`--range` 里的 `Sheet1!` 前缀不能替代 sheet 定位**：仍必须传 `--sheet-id` / `--sheet-name`。
+   - ⚠️ **A1 引用含 `!` 时整段用单引号包裹**（`--range 'Sheet1!A1:B2'`，挡 bash history expansion；别用 `set +H`，sh/dash 下非法）。sheet 名含 `-`/空格需内层再包单引号时用 `'\''` 转义：`--source ''\''Sales-2025'\''!A1:D100'`。

-- **envelope**：所有 shortcut 返回统一外层结构 `{ok, identity, data, ...}`。正文里 `envelope.data` 指业务数据层（如 `+csv-get` 的 `annotated_csv`）；写操作不会自动回读，如需校验请自行调用对应的 `+*-list` / `+*-get` / `+cells-get`。

 ## 复合 JSON / 大入参：优先 stdin
 
-flag 帮助里标注支持 **Stdin** 的入参，当 payload 较大、含换行 / 引号等特殊字符，或已经落在某个文件里时，优先用 stdin（`-`）传入，避免命令行超长与 shell 转义问题。
-
-推荐写法：payload 写到用户项目目录之外的临时文件（放系统临时目录，避免污染项目），再用 stdin 喂进去：
+大 payload（`--operations` / `--cells` / `--sheets` / `--styles` / `--properties`…）、或含换行 / 引号 / `!` 等特殊字符时，优先 heredoc stdin（`-`）传入，避免命令行超长与 shell 转义问题：
 
 ```bash
-# TMPFILE 指向系统临时目录下的 payload 文件（脚本里用 tempfile.gettempdir() / os.tmpdir() 等取临时目录）
-lark-cli sheets +cells-set --url "..." --sheet-name "Sheet1" --range "A1:B2" --cells - < "$TMPFILE"
+lark-cli sheets +batch-update --url "..." --yes --operations - <<'JSON'
+[{"shortcut":"+cells-set","input":{...}}]
+JSON
 ```
 
-**参数含特殊字符（`!` / 引号 / 空格 / 非 ASCII）时，用单引号包裹该参数即可，不要起手 `set +H` 之类的 shell 开关来防转义。** `set +H`（关 bash history expansion）在 `sh` / `dash` 下是非法选项（`set: Illegal option -H`）、会让整条命令直接失败；而单引号挡得住 `!` 的 history expansion（否则报 `event not found`），对 bash 与 `sh` / `dash` 一致安全。参数本身含单引号、或 payload 较大时，按上文走 stdin。
-
-**`@file` 接绝对路径会被拒，且被拒后不要照报错提示做。** `@file` 出于安全只接受 cwd 下的相对路径，传 cwd 之外的绝对路径会被拒。此时报错会建议"先 cd 到目标目录，或改用相对路径"——**两条都不要照做**：cd 过去、或把临时文件写进用户项目目录，都会污染工作目录。正解是改用 stdin（`--<flag> - < 文件`）。

 ## 使用场景
 
-读写图表对象。本 reference 覆盖 4 个 shortcut：
+读写图表对象。基础创建和常用更新优先用语义 shortcut，只在高级配置时使用原始 snapshot：
 
 | 操作需求 | 使用工具 | 说明 |
 |---------|---------|------|
 | 查看已有图表 | `+chart-list` | 获取图表的类型、数据源和样式配置 |
-| 创建/更新/删除图表 | `+chart-{create|update|delete}` | 对图表对象执行写入操作 |
+| 按类型和范围创建基础图 | `+chart-create-basic` | 支持 column/bar/line/area/pie/scatter/combo/radar、行/列方向与整图配色；无需构造 snapshot |
+| 修正已有图表的数据范围或方向 | `+chart-data-update` | 服务端重建数据映射，保留标题、样式、位置和尺寸 |
+| 批量创建或更新多个独立图表 | `+batch-update --continue-on-error` | 保留成功图表，并逐项返回失败原因；只重试失败项 |
+| 更新标题、轴、图例、标签、堆叠、平滑或整图配色 | `+chart-config-update` | 无需回写 snapshot，未传字段保持不变 |
+| 高级创建/更新、删除图表 | `+chart-{create|update|delete}` | 按系列/数据点精细设置等高级需求才使用原始 properties |
 
-典型工作流：先读取现有图表了解配置 → 执行创建/更新/删除 → 再次读取验证结果。
+典型工作流：先确认表头和精确数据范围，用 `+chart-create-basic` 一次创建并尽量在同次调用中带上已知标题/轴/标签要求；创建后用 `+chart-list` 验证。已有图表的数据范围或方向错误时用 `+chart-data-update`，常用配置修正用 `+chart-config-update`。只有用户要求单个系列、数据点或高级引擎字段时，才读取现有 snapshot 并调 `+chart-update --properties`。不要为了常用配置先输出整份 schema，也不要删除重建已经创建成功的图表。
+
+**多图表工作流**：先完成所有辅助数据和表头，列出每张目标图的类型、精确数据范围、标题和落点；确认清单后，用一次 `+batch-update --continue-on-error` 批量执行 `+chart-create-basic`。图表之间独立时允许部分成功：按返回的逐项结果定位失败图表，只重试失败项，不要重复创建成功图表。批次后每个受影响的 sheet 各调用一次 `+chart-list`，验证数量、类型、系列和范围。数据尚未稳定时不要提前创建图表；已经成功创建的图表有数据源差异时批量使用 `+chart-data-update`，有配置差异时批量使用 `+chart-config-update`，不要删除重建。
+
+**数量词必须展开**：用户说“每个 / 每天 / 分别 / 逐一 / 各一张图”时，先从数据中数出实体数 `N`，把这 `N` 张图逐项写进清单，再加上其它汇总图得到目标总数 `M`；一个包含全部实体的多系列图不能替代这 `N` 张独立图。批次前断言 operations 中恰有 `M` 个图表创建，批次后断言图表总数、逐图标题与实体集合一致。
+
+**范围与系列前置校验**：清单中同时记录每张图的表头范围、纳入列、明确排除列、数据方向和预期系列数。表头在首列时用默认 `--data-direction column`；表头在首行、每行代表一个系列时用 `--data-direction row`。创建前根据实际表头确认边界，不凭字母猜范围；创建后范围、方向或系列数不符时，使用 `+chart-data-update` 修正，服务端会重建 `refs` / `dim1` / `dim2.series` 并保留其它配置，不要删除后重建。批次跨多个 sheet 时，每个受影响的 sheet 各调用一次 `+chart-list`。
+
+**整图配色优先走语义参数**：只要求统一主题或一组系列颜色时，在创建时传 `--color-palette` 或 `--colors`，已有图表用 `+chart-config-update` 更新；二者互斥。只有指定某个系列或某个数据点的颜色时才使用原始 snapshot。

 **常见配置错误（必须注意）**：
 - **图表类型选择错误**：用户说"堆积柱形图/百分比堆积"时，应在 `properties.snapshot.plotArea.plot.extra.stack` 中配置堆叠；百分比堆叠需在该 stack 下设置 `percentage: true`。用户说"占比/比例"时，优先考虑饼图或百分比堆积图。注意区分 `column`（柱形图，纵向）与 `bar`（条形图，横向）是两个不同的 type 取值，"对比/各 XX" 类纵向柱默认用 `column`
