chore(release): rehearse 0.32.5-rc.3 from the computer-use branch
A release candidate built from task/227 (PR #870) before it is merged, to
run the whole release pipeline on computer use: the signed and notarized
macOS app with codeg-computer-helper.app, and every desktop, server and
Docker target. It is not on main and is not meant for general use.
发布流水线预演：电脑操作分支（task/227，PR #870）合入前构建的候选版本，用来把整条发布流水线跑一遍。不在 main 上，不供日常使用。
