name: OTA Frontend Build & Sign

# 前端 OTA 升级包构建 + 签名 + 上传 artifact
# 触发: 仅手动 (workflow_dispatch), 发版前用
#   - 主分支 push 的自动 OTA 生成已并入 docker-build.yml (随镜像发布), 本 workflow 不再监听 push 避免重复构建
# 输入: sequence / notes / min_binary (可覆盖默认)
# Secret 依赖: MINISIGN_PRIVATE_KEY (整段 .key 文件内容, 含首行 untrusted comment)
# 注意: 此 workflow 不会修改 src-tauri/tauri.conf.json 里的 pubkey,
#       换密钥请手动改 conf 并 commit.
