fix(release+docs): 让 -dws-devapp 可被'装最新'，文档去掉写死版本号

问题：-dws-devapp 全系列被 goreleaser 标成 prerelease（semver 后缀触发），
GitHub 的 /releases/latest 跳过 prerelease，导致：
- 文档写死的 v1.0.53 每发一版就过期（现已落后到 v1.0.60）
- releases/latest/download 与 install.sh 的 latest 解析对 devapp 全失效

修复：
- release.yml 新增一步，仅当 tag 含 -dws-devapp 时把该 release 翻成
  非 prerelease 并标记 latest；goreleaser 仍保持 prerelease: auto，
  不影响 -dev.x 等其他预发版的语义
- robot-quickstart.md 三处下载/链接改用 releases/latest，去掉写死版本号，
  提示语软化为'能打印版本即成功'
