docs: simplify backend changelog guide

修改原因：hl-ui changelog loop 需要把前端消费进度回写到契约源，避免领取、实现状态与实际交付脱节。

修改内容：将 frontend_status 与已有 legacy frontend 同步为 implemented，记录负责人 hl-ui-codex，并关联 mmg/hl-ui@41f307090eccfdf3d06deabce8bc4f3d2be9a99a；发布和验收字段保持不变。

实际验证：回写器已校验目标文件、状态单调性、提交范围和 Front Matter 内容，提交只包含当前 changelog。

+# 后端 API Changelog 推送说明
+
+接口发生新增、修改或删除时，在 `hl-api-changelog` 仓库提交一份 changelog。
+
+## 1. 放在哪里
+
+- 管理后台：`changelogs-v2/YYYY-MM/`
+- 小程序：`changelogs-v2-mp/YYYY-MM/`
+
+文件名：
+
+```text
+DD_issue_业务标题-{新增接口|修改接口|删除接口}-{管理后台|小程序端}.md
+```
+
+例如：
+
+```text
+changelogs-v2/2026-07/24_5205_车务首页汇总状态补全-修改接口-管理后台.md
+```
+
+日期使用提交时的上海日期；不要把“前端待处理”“已完成”等状态写进文件名。
+
+## 2. 写什么
+
+可以复制仓库根目录的 `CHANGELOG_TEMPLATE.md`，至少写清：
+
+- 关联的 Issue 和后端 PR；
+- 接口路径和 HTTP 方法；
+- 新增、修改或删除的请求/响应字段；
+- 字段必填性、枚举、状态、空值、金额和兼容规则；
+- 前端需要做什么；
+- 后端测试、部署和网关验证结果。
+
+元数据中：
+
+```yaml
+backend_status: "deployed"
+gateway_status: "verified"
+frontend_status: "pending"
+frontend_owner: ""
+frontend_ref: ""
+target_release: ""
+verified_at: ""
+```
+
+- 需要前端修改：`frontend_status: "pending"`
+- 不需要前端修改：`frontend_status: "not_required"`
+- 后端不要代替前端填写 `implemented`、`released` 或 `verified`
+
+## 3. 校验
+
+在 `hl-api-changelog` 仓库执行：
+
+```powershell
+npm test
+npm run check:filenames -- --base origin/main --head HEAD
+npm run check:frontmatter -- --base origin/main --head HEAD
+```
+
+确保正文没有 `TODO`、`待补充` 或模板占位符。
+
+## 4. 提交和推送
+
+只暂存本次 changelog 文件：
+
+```powershell
+git status --short
+git add -- changelogs-v2/2026-07/24_5205_车务首页汇总状态补全-修改接口-管理后台.md
+git diff --cached --check
+git commit -m "docs: hand off API contract (#5205)"
+git push -u origin <任务分支>
+```
+
+然后向 `main` 创建 PR。不要提交其他任务的 changelog、`.tmp-*` 文件或任何凭据。

+# API Changelog 前端消费状态协作说明
+
+## 可直接转发给前端的通知
+
+API changelog 从 `hl-changelog/v2` 开始记录前端消费进度。后端交接时会填写：
+
+```yaml
+backend_status: "deployed"
+frontend_status: "pending"
+frontend_owner: ""
+frontend_ref: ""
+target_release: ""
+verified_at: ""
+```
+
+请前端在领取、实现、发布和页面验证时更新对应状态，并填写可追溯的前端 PR、提交或发布版本。
+
+这不会把前端工作纳入后端工单验收，也不要求在 `hl-ui` 创建配合工单。它只用于区分：
+
+- 后端接口是否已经部署并验证；
+- 前端是否已经领取；
+- 前端代码是否已经实现；
+- 页面是否已经发布并验证。
+
+只有 `frontend_status: "verified"` 才表示用户页面形成完整闭环。
+
+## 状态流转
+
+```text
+pending → claimed → implemented → released → verified
+```
+
+不需要前端修改时：
+
+```text
+not_required
+```
+
+| 状态 | 含义 | 必填证据 |
+|---|---|---|
+| `not_required` | 不需要前端修改 | 不填写前端负责人、引用和版本 |
+| `pending` | 等待前端领取 | 无 |
+| `claimed` | 前端已领取 | `frontend_owner` |
+| `implemented` | 前端代码已实现 | `frontend_owner`、`frontend_ref` |
+| `released` | 已发布 | 再填写 `target_release` |
+| `verified` | 页面已验证 | 再填写 `verified_at` |
+
+跨级迁移会被自动校验拒绝。状态回退或改为/取消 `not_required` 时必须填写原因。
+
+## 更新命令
+
+领取：
+
+```powershell
+hl changelog transition 5205 D:/path/changelog.md claimed `
+  --owner frontend-team --write
+```
+
+实现：
+
+```powershell
+hl changelog transition 5205 D:/path/changelog.md implemented `
+  --owner frontend-team `
+  --frontend-ref "mmg/hl-ui@abc1234" `
+  --write
+```
+
+发布：
+
+```powershell
+hl changelog transition 5205 D:/path/changelog.md released `
+  --target-release "test-2026.07.24" `
+  --write
+```
+
+验证：
+
+```powershell
+hl changelog transition 5205 D:/path/changelog.md verified `
+  --verified-at "2026-07-24" `
+  --write
+```
+
+命令默认只预览；只有 `--write` 才修改文件。写入命令会自动获取 `changelog` 单写租约。
+
+## 职责边界
+
+后端负责：
+
+- 完成后端测试、部署和网关验证；
+- 初始化 v2 元数据；
+- 需要前端时设置 `pending`，不需要时设置 `not_required`；
+- 不替前端填写 `implemented`、`released` 或 `verified`。
+
+前端负责：
+
+- 领取时填写负责人；
+- 实现后填写前端引用；
+- 发布后填写目标版本或环境；
+- 页面验证后填写验证日期。
+
+QA 或产品可以协助更新 `verified_at`，但必须基于实际页面验证，不能只根据接口成功或代码已合并标记完成。
+
+## 存量文档
+
+- 新 changelog 全部使用 `hl-changelog/v2`。
+- `hl-changelog/v1` 继续可读和索引，不强制一次性迁移。
+- 文件名带“前端待处理”不代表真实状态；需要继续流转时补充 v2 元数据。
+- 不通过重命名表达消费状态，避免破坏文件名校验和历史链接。
