fix(ci/client): mac 端 job runs-on mac→nas(匹配实际 runner label)

mac runner(mac-pangolin-2)启动脚本注册 label 为 nas:host;此前靠手动加的 mac
label 让 runs-on:mac 命中,但 runner 重启(经启动脚本)会重注册成 nas、丢掉 mac
label → build-android/macos/ios/release-deploy 无 runner 可接、永久排队。改成
runs-on:nas 匹配实际 label,抗重启漂移(nas runner 即这台 mac,唯一)。windows
job 仍 runs-on:windows(windows runner)。
