ci: 改用 host-mode runner,删掉无效的 container.volumes

act_runner v0.4.1 在 label 带 docker:// 的情况下会静默丢弃 jobs.<id>.container
块和 container.options 里的 -v(实测两条都不工作),改让 step 直接在 runner 容器
内跑,/blog-public 由 runner docker-compose 直接 bind 到 NAS。

- 删 jobs.build.container 块(被 runner 忽略,留着只是误导)
- 删 verify mount 步骤(host 模式下挂载是 compose 层保证的)
- 删 paths-ignore: deploy/**(repo 里没有)
- Alpine runner 用 apk 装 curl/tar/rsync/git/bash
