What plugin management does now lives in `dsh-plugin-manager`, a boot-group
package beside `app-boot`: `PluginInstaller` runs pnpm, probes, and judges new
packages over the profile on disk, and `PluginManager` adds every operation
over the booted tree, each refusal a `PluginOperationError` with a `plugins/*`
code and no Remote protocol attached. The manager reads the profile runtime,
the preset roster, and the running-agent count through per-call readers, and
the roster only as `PresetLayers`, so the package depends on neither the
roster nor the agent registry.
`dsh-host-plugin-manager` keeps `pluginManager` and the `plugins` Remote as a
relay: one Remote method per manager method, and one exhaustive switch
turning a failure into the Remote error of the same code (`plugins/bad-request`
into `gateway/bad-request`). Its `./types` re-exports the manager's types, so
`api-remotes` and the client import one vocabulary unchanged.
`dsh plugin add` and `remove` now run the installer instead of a bare pnpm
forwarder: every new package is probed, a package that declares neither a
bundle nor a plugin module is removed again with its reason, and newly
installed bundles are enabled as before. Other pnpm verbs still forward.
