refactor(cli)!: namespace the profile and bundle manifests under dsh.profile and dsh.bundle

A profile manifest and a bundle manifest are different kinds and shared one
flat `dsh` section: `dsh.plugins` listed bundles (not plugins) and `dsh.patch`
declared a bundle's layer. Each kind now names its role — a bundle declares
`dsh.bundle.patch`, a profile declares `dsh.profile.bundles` — so a
package.json states which role it plays and the list name matches its contents.

`DEFAULT_PROFILE_PLUGINS` becomes `DEFAULT_PROFILE_BUNDLES`, and
`DshManifestSection` splits into `DshBundleManifest`/`DshProfileManifest`.
Pre-release: no compatibility shim; turtle-ui moved with it (bd5ff10).

-Profile 组合包：在 manifest（元数据清单）中声明 `"dsh": { "patch": "./cordis.patch.yml" }` 的 npm 包，因此可作为 patch 层安装进 `dsh --profile` 组合（[profile 契约](../ui/app-boot/README.md#profiles)）。组合包的实体是它的 patch 列表；有些组合包还附带由其 patch 挂载的运行时粘合插件。
