docs(dev-environment-setup): /environment/refresh 补充重新加载登录环境变量语义 (#24)

## 变更说明 / Description

配合客户端 PR
[desirecore/desirecore#808](https://github.com/desirecore/desirecore/pull/808)：`POST
/api/runtime/environment/refresh` 端点现在除清检测缓存外，还会**重新抓取登录 shell / Windows
注册表环境并精确同步到 `process.env`**。本 PR 更新 `dev-environment-setup` skill 文档，让
AI 在「用户改了 `.zshrc` / `setx` 但工具看不到」时能主动调用该端点（无需用户重启 App）。

Companion to client PR desirecore#808: the `/environment/refresh`
endpoint now also reloads login-shell / Windows-registry env and
precise-syncs into `process.env`. This PR updates the
`dev-environment-setup` skill docs so the AI proactively calls it when a
user reports a freshly-changed env var that tools can't see.

## 改动 / Changes

- `references/desirecore-runtime.md`：第三节端点表更新 + 第七节扩展（重新加载语义 + `envDiff`
返回结构 + 「何时主动调用」触发场景 + 局限）
- `SKILL.md` / `SKILL.zh-CN.md`：L1 路由表新增「用户改了 `.zshrc` / 环境变量 / 代理 /
`setx` 但工具看不到 → 刷新端点」+ 重要约束第 3 条扩展（中英双语同步）
- `version` 2.0.3 → 2.0.4；并修正 #16 起遗留的 `source_hash` stale 值（`7e4baaf` →
`748e754b`，已用 `scripts/i18n` 同款算法验证）

## 说明 / Notes

- 该 skill 为 `translated_by: human`，中英两份已手动同步
- 文档描述的端点能力随客户端 PR desirecore#808 发布；旧客户端调用该端点仍只清检测缓存（不报错），文档短暂超前可接受
