feat(mail): add email template management + --template-id on compose (#642)

Browse Source 
- `mail +template-create` / `mail +template-update` — manage personal
    email templates (name, subject, body, recipients, attachments,
    inline images).
  - `--template-id` on `+send` / `+draft-create` / `+reply` /
    `+reply-all` / `+forward` — apply a saved template when composing.
    Recipients / subject / body / attachments merge into the draft;
    explicit user flags take precedence.

# mail +template-create
> **前置条件：** 先阅读 [`../../lark-shared/SKILL.md`](../../lark-shared/SKILL.md) 了解认证、全局参数和安全规则。
创建一个新的个人邮件模板。适用于需要长期复用的邮件框架，例如周报、客户通知、请假申请等。
不要用此命令发送邮件；模板只是预置内容，实际发信请使用 `+send` / `+draft-create` 等 shortcut 配合 `--template-id` 套用。
如需修改已有模板，使用 [`lark-cli mail +template-update`](./lark-mail-template-update.md)。
## 安全约束
- **模板正文也会被当作邮件内容对外发送**——所有邮件域的通用安全规则（prompt injection、XSS、敏感信息）同样适用。
- **不要把模板内容以文本形式输出给用户请求最终确认**。命令返回 `template_id` 后，引导用户在飞书邮箱 UI 里打开模板核对。
- 用户模板上限 **20** 个，单模板 `template_content` 上限 **3 MB**；超限会被后端拒绝。
## 命令
```bash
# 纯 HTML 模板
lark-cli mail +template-create --as user \
--name '周报模板' \
--subject '本周进展' \
--template-content '<p>大家好，请见本周进展：</p><ul><li>……</li></ul>'
# 带 HTML 内嵌图片 + 非 inline 附件
lark-cli mail +template-create --as user \
--name '客户通知模板' \
--subject '产品更新' \
--template-content '<p>新版本上线：</p><img src="./banner.png"><p>附上发版说明。</p>' \
--attach './release-notes.pdf'
# 从文件加载正文
lark-cli mail +template-create --as user \
--name '请假申请' \
--template-content-file './leave.html' \
--to 'manager@example.com,hr@example.com'
# Dry Run
lark-cli mail +template-create --as user \
--name '周报模板' --template-content '<p>x</p>' --dry-run
```
## 参数
| 参数 | 必填 | 说明 |
|------|------|------|
| `--name <text>` | 是 | 模板名称，≤100 字符 |
| `--subject <text>` | 否 | 默认主题 |
| `--template-content <html>` | 否* | 模板正文。HTML 首选；支持 `<img src="./local.png" />` 相对路径自动上传到 Drive 并改写为 `cid:` |
| `--template-content-file <path>` | 否* | 从文件加载正文内容；与 `--template-content` 互斥 |
| `--plain-text` | 否 | 标记为纯文本模式（`is_plain_text_mode=true`）。仍可带内嵌图片，但 `+send --template-id` 套用时会走 plain-text 正文拼接 |
| `--to <emails>` | 否 | 默认收件人列表，逗号分隔，支持 `Name <email>` 格式 |
| `--cc <emails>` | 否 | 默认抄送 |
| `--bcc <emails>` | 否 | 默认密送 |
| `--attach <paths>` | 否 | 非 inline 附件路径，逗号分隔。每个文件按 `--attach` 书写顺序上传到 Drive |
| `--mailbox <email>` | 否 | 所属邮箱，默认 `me`（当前用户主邮箱） |
| `--dry-run` | 否 | 仅打印计划中的 API 调用链，不真实执行 |
\* `--template-content` / `--template-content-file` 二选一；两者都留空则模板正文为空（用户之后可通过 `+template-update` 补充）。
## HTML 内嵌图片自动上传
正文中所有不带 URI scheme 的 `<img src="./local.png">`（相对路径）会被：
1. 上传到 Drive（≤20 MB 走 `medias/upload_all`；>20 MB 走 `upload_prepare + upload_part + upload_finish`）
2. 生成 UUIDv4 CID
3. HTML 改写为 `<img src="cid:<uuid>">`
4. 在 `attachments[]` 追加 `{id: <file_key>, cid, is_inline: true, filename, attachment_type}`
带 URI scheme 的 `<img src="https://...">` 或 `<img src="cid:...">` 跳过上传。
## SMALL vs LARGE 附件
附件分为 SMALL（`attachment_type=1`，内嵌到 EML）和 LARGE（`attachment_type=2`，由服务端渲染成下载链接）。切换阈值：
- **本地单文件大小**：≤20 MB 用 `upload_all`，>20 MB 分块上传（与 SMALL/LARGE 无关，只影响 Drive 上传路径）。
- **累计 EML 投影**：`subject + to + cc + bcc + template_content + base64 附件体积`；同批次累计超过 **25 MB** 后，剩余的非 inline 附件标 `LARGE`，inline 图片不能切换到 LARGE（HTML `cid:` 引用要求 MIME part 存在）。
两套判定相互独立。
## 顺序约束
- inline 图片按正文中 `<img>` 出现顺序处理
- 非 inline 按 `--attach` 书写顺序处理；重复路径不会去重
## 返回值
成功返回：
```json
{
"template": {
"template_id": "712345",
"name": "周报模板",
"subject": "本周进展",
"template_content": "<p>...</p>",
"is_plain_text_mode": false,
"tos": [{"mail_address": "alice@example.com"}],
"attachments": [...],
"create_time": "1714000000000"
}
}
```
- `template_id` 为十进制字符串。后续套用模板时 `--template-id <template_id>`。

# mail +template-update
> **前置条件：** 先阅读 [`../../lark-shared/SKILL.md`](../../lark-shared/SKILL.md) 了解认证、全局参数和安全规则。
更新已有的个人邮件模板（全量替换式更新）。支持 `--inspect` 只读 projection、`--print-patch-template` 打印 patch 骨架、`--patch-file` 结构化 patch、以及扁平的 `--set-*` flag。
> **⚠️ 后端无乐观锁 → last-write-wins**。并发更新可能丢失最近的改动；CLI 在每次成功更新时会在 stderr 打印一条 warning 提示。
如需创建新模板，使用 [`lark-cli mail +template-create`](./lark-mail-template-create.md)。
## 工作模式
| 入口 | 行为 | 是否写库 |
|------|------|---------|
| `--print-patch-template` | 打印 `--patch-file` 的 JSON 骨架 | 否（纯本地） |
| `--inspect` | 返回当前模板完整 projection | 否（只 GET） |
| `--set-*` / `--attach` | 扁平 flag 合并后 PUT | 是 |
| `--patch-file` | 结构化 patch + 扁平 flag 合并后 PUT | 是 |
## 命令
```bash
# 查看当前状态（不修改）
lark-cli mail +template-update --as user --template-id 712345 --inspect
# 打印 patch 骨架并保存
lark-cli mail +template-update --as user --print-patch-template > /tmp/tpl-patch.json
# 用扁平 flag 改 subject + cc
lark-cli mail +template-update --as user --template-id 712345 \
--set-subject '每周五发布' \
--set-cc 'manager@example.com'
# 用 patch 文件做结构化更新（支持 is_plain_text_mode 翻回 false 等 tri-state 场景）
lark-cli mail +template-update --as user --template-id 712345 \
--patch-file /tmp/tpl-patch.json
# 追加新附件
lark-cli mail +template-update --as user --template-id 712345 \
--attach './appendix.pdf'
```
## 参数
### 定位
| 参数 | 必填 | 说明 |
|------|------|------|
| `--template-id <id>` | 是* | 模板 ID，十进制整数字符串 |
| `--mailbox <email>` | 否 | 所属邮箱，默认 `me` |
\* `--print-patch-template` 场景下可省略。
### 只读 / 输出
| 参数 | 说明 |
|------|------|
| `--inspect` | 只 GET，不修改；返回完整模板 projection |
| `--print-patch-template` | 打印 patch 骨架（不访问网络），保存后作为 `--patch-file` 的起点 |
### 扁平 set-* flag（直接指定新值）
| 参数 | 说明 |
|------|------|
| `--set-name <text>` | 替换名称，≤100 字符 |
| `--set-subject <text>` | 替换默认主题 |
| `--set-template-content <html>` | 替换正文。支持 `<img src="./local.png" />` 相对路径自动上传并改写 |
| `--set-template-content-file <path>` | 从文件加载替换正文；与 `--set-template-content` 互斥 |
| `--set-plain-text` | 标为纯文本模式（置 true）。**不提供不会置 false**；要把 HTML 模板翻回 false，请用 `--patch-file` 的 `{"is_plain_text_mode": false}` |
| `--set-to <emails>` | 替换默认收件人列表 |
| `--set-cc <emails>` | 替换默认抄送 |
| `--set-bcc <emails>` | 替换默认密送 |
| `--attach <paths>` | 追加非 inline 附件（按书写顺序），不替换已有附件 |
### 结构化 patch
| 参数 | 说明 |
|------|------|
| `--patch-file <path>` | JSON patch 文件。结构同 `--print-patch-template` 输出；任何 **非空字段**覆盖当前模板对应字段 |
patch-file 字段（全部可选，未提供的字段保持当前模板原值）：
```json
{
"name": "string (≤100 chars, optional)",
"subject": "string (optional)",
"template_content": "string (HTML 或纯文本；本地 <img src> 会自动上传)",
"is_plain_text_mode": "bool (optional) — 显式 true/false 都生效",
"tos": [{"mail_address": "...", "name": "..."}],
"ccs": [{"mail_address": "...", "name": "..."}],
"bccs": [{"mail_address": "...", "name": "..."}]
}
```
## 合并策略
1. `GET` 当前模板完整内容
2. 先应用扁平 `--set-*` flag（非空即覆盖）
3. 再应用 `--patch-file`（非空字段覆盖）——patch-file 优先级高于扁平 flag
4. 重新扫描新正文中的 `<img>` 本地路径，上传到 Drive 并改写为 `cid:`
5. `--attach` 追加的新附件以新的 `emlProjectedSize` 独立计算 SMALL/LARGE
6. 附件按 `(id, cid)` 去重后 `PUT` 整个模板
> **所有原有附件保留**：只追加 `--attach` 新附件；如需删除已有附件，目前只能通过 `--patch-file` 的 `template_content` 改写正文去除相应 `<img>` 引用，或使用原生 API 整块重写。
## DryRun 行为
- 默认：打印 `GET /user_mailboxes/:id/templates/:tid` + Drive 上传步骤（如有 `<img>` 或 `--attach`）+ `PUT` 步骤。
- `--inspect`：只打印 `GET`。
- `--print-patch-template`：打印骨架，不走任何 API。
## 返回值
成功返回：
```json
{
"template": {
"template_id": "712345",
"name": "周报模板",
"subject": "每周五发布",
"template_content": "...",
"is_plain_text_mode": false,
"tos": [...],
"attachments": [...],
"create_time": "1714000000000"
}
}
```
`--inspect` 返回同样结构；`--print-patch-template` 返回 patch JSON 骨架。
