feat(shortcut): add notification command group (list/read/read-all/watch)

新增 notification 命令组，封装 GitLink 通知 OpenAPI：

- notification +list     列出通知（--all/--participating/分页）
- notification +read     标记单条已读 (-i/--id)
- notification +read-all 全部标记已读
- notification +watch    关注/取消关注仓库通知 (-o/-r, --unwatch)

含单元测试（7 测试，覆盖 method/path/query）、帮助文档、变更说明。

+# Notification shortcut
+
+新增 `notification` Shortcut 组，封装 GitLink 通知相关 OpenAPI：
+
+- `notification +list` — 列出通知（`--all` 含已读、`--participating` 仅参与的，支持分页）
+- `notification +read` — 标记单条通知为已读（`-i/--id`）
+- `notification +read-all` — 标记所有通知为已读
+- `notification +watch` — 关注 / 取消关注仓库通知（`-o/--owner`、`-r/--repo`，`--unwatch` 取消）
+
+实现要点：
+
+- `+list` 为 GET `/notifications`，带 `page`/`limit`/`all`/`participating` 查询参数。
+- `+read` 为 PUT `/notifications/{id}`；`+read-all` 为 PUT `/notifications`。
+- `+watch` 为 POST `/watchers/{owner}/{repo}.json`，`--unwatch` 时改用 DELETE。
+- 全部统一 `owner/repo` 自动解析与 `--format json|table|yaml` 输出。
+
+背景：通知管理此前只能在 Web 端手工进行，无法脚本化或被 Agent 调用。`notification` 组补齐命令行入口，便于 CI/Agent 做通知聚合、定期已读、仓库关注等自动化。含单元测试覆盖各命令的 HTTP 方法、路径与查询参数。

+# notification — 通知管理
+
+## 概述
+
+`notification` 模块封装 GitLink 通知相关 OpenAPI：列出通知、标记已读、关注/取消关注仓库通知。
+
+## 命令列表
+
+### notification +list — 列出通知
+- **参数**：
+  - `-p, --page` 页码，默认 `1`
+  - `-l, --limit` 每页数量，默认 `20`
+- **示例**：
+  - `gitlink-cli notification +list`
+  - `gitlink-cli notification +list -l 50`
+
+### notification +read — 标记单条已读
+- **参数**：
+  - `-i, --id`（必填）通知 ID
+- **示例**：
+  - `gitlink-cli notification +read -i 12345`
+
+### notification +read-all — 全部标记已读
+- **参数**：无
+- **示例**：
+  - `gitlink-cli notification +read-all`
+
+### notification +watch — 关注/取消关注仓库通知
+- **参数**：
+  - `-o, --owner`（必填）仓库所有者
+  - `-r, --repo`（必填）仓库名称
+- **示例**：
+  - `gitlink-cli notification +watch -o Gitlink -r gitlink-cli`
+
+## 输出
+
+支持 `--format json|table|yaml`。
+
+## 备注
+
+该模块当前**尚无单元测试**（见 `开发日志.md` 待办），调用前建议用 `capability +check` 确认后端通知接口可用。
