feat: support visible_rule for form questions

Form questions can now carry a visible_rule (display condition) so a
question shows only when earlier questions match the rule. The rule shares
the exact same structure as the view filter, so extract that structure into
a single shared reference (lark-base-filter-condition.md) that both
view-set-filter and visible_rule point to.

- create/update shortcuts: document visible_rule in --questions help and
  transcribe the questions body (including visible_rule) into dry-run output
- skill refs: add visible_rule sections to form-questions create/update,
  note it is only needed when the user asks for a display condition, and
  that form-questions-list returns it verbatim
- tests: pin flag help, verbatim visible_rule passthrough on
  create/update/list, and add dry-run E2E coverage

+# Base Filter 条件结构（公共协议）
+
+两者 JSON 结构完全一致，仅「条件引用的对象」不同：视图 `filter` 引用**数据表字段**，表单 `visible_rule` 引用**同一表单内的其他题目**。
+
+## 1. 顶层结构
+
+- 必须是 JSON 对象。
+- 顶层结构是 `{logic?, conditions?}`。
+- `logic` 默认 `and`；推荐只用 canonical 值 `and` / `or`。
+- `conditions` 默认空数组。
+- 每条条件写成 tuple：`[field, operator, value?]`。
+- `empty` / `non_empty` 可写成 2 项：`[field, "empty"]`、`[field, "non_empty"]`。
+
+```json
+{
+  "logic": "and",
+  "conditions": [
+    ["状态", "intersects", ["Doing"]],
+    ["负责人", "intersects", [{ "id": "ou_xxx" }]],
+    ["截止时间", "empty"]
+  ]
+}
+```
+
+清空写法：
+
+```json
+{
+  "conditions": []
+}
+```
+
+## 2. operator
+
+可用 operator：
+- `==`
+- `!=`
+- `>`
+- `>=`
+- `<`
+- `<=`
+- `intersects`
+- `disjoint`
+- `empty`
+- `non_empty`
+
+## 3. value 写法
+
+value 类型取决于条件引用对象（字段 / 题目）的类型。
+
+### `text`
+
+用字符串：
+
+```json
+["标题", "intersects", "发布"]
+```
+
+### `location`
+
+location 筛选只按 `full_address` 字符串匹配，不能直接按经纬度筛选；优先使用 `intersects` 做包含匹配，例如查深圳：
+
+```json
+["位置", "intersects", "深圳"]
+```
+
+不推荐写 `["位置", "==", "深圳"]` 这类精确匹配，除非确保筛选值与完整 `full_address` 完全一致。
+
+### `number` / `auto_number`
+
+用数字：
+
+```json
+["工时", ">=", 3.5]
+```
+
+### `select`
+
+用选项名数组：
+
+```json
+["状态", "intersects", ["Doing", "Blocked"]]
+```
+
+### `user` / `created_by` / `updated_by`
+
+用对象数组：
+
+> **人员筛选：不要猜 ID。** 不知道 `open_id` 时，先用 `lark-contact` 查 id：`lark-cli contact +search-user --query "<姓名/邮箱/手机号>" --as user`。
+
+```json
+["负责人", "intersects", [{ "id": "ou_xxx" }]]
+```
+
+### `group_chat`
+
+用对象数组：
+
+> **群组筛选：不要猜 ID。** 不知道 `chat_id` 时，先用 `lark-im` 搜群：`lark-cli im +chat-search --query "<群名关键词>" --as user`；取结果里的 `oc_xxx`。
+
+```json
+["负责群", "intersects", [{ "id": "oc_xxx" }]]
+```
+
+### `link`
+
+用记录 id 对象数组：
+
+```json
+["关联任务", "intersects", [{ "id": "rec_xxx" }]]
+```
+
+### `checkbox`
+
+用布尔值：
+
+```json
+["完成", "==", true]
+```
+
+### `datetime` / `created_at` / `updated_at`
+
+用相对时间关键字或 `ExactDate(...)`：
+
+```json
+["截止时间", "==", "ExactDate(2026-01-01)"]
+```
+
+```json
+["截止时间", "==", "ExactDate(2026-01-01 11:30)"]
+```
+
+```json
+["截止时间", "==", "Today"]
+```
+
+可用关键字：
+- `Today`
+- `Yesterday`
+- `Tomorrow`
+
+### `formula` / `lookup`
+
+- 筛选值类型由字段计算结果类型动态决定。
+- 拿不准时，先把 `value` 当作单个字符串填入做一次尝试。
+- 如果报错，再按错误提示把 `value` 改成对应类型。
+
+字符串示例：
+
+```json
+["风险说明", "intersects", "高风险"]
+```
+
+数字示例：
+
+```json
+["汇总分", ">=", 80]
+```
+
+## 4. 易错点
+
+- 不要再写旧对象风格：`{"field_name":...,"operator":...}`。
+- `user` / `group_chat` / `link` 不要写成单个标量。
+- `empty` / `non_empty` 不要硬塞无意义的 value。
+- 日期条件稳定写法用 `ExactDate(...)` 或 `Today` / `Yesterday` / `Tomorrow`。
+- `formula` / `lookup` 的 value 形状不固定；拿不准时先读当前配置或字段定义，或根据错误提示修正类型。
+
+## 5. 参考
