DogEgg-alR/dsh-plugin-installer

Install, update and remove DSH plugins from a tab in the Plugins page. Installs call the profile's in-process pluginManager service, so a plugin can be added while the desktop app is running instead of only through the CLI. Updates are delegated to dsh-market's public update API v1 (required for that section) and show the reported phase, percent and downloaded bytes as a progress bar, with rollback when the market reports a restore point. When removal is refused because the bundle is in use, it disables the bundle, drops it from the profile manifest, and queues the leftover files under the profile for a sweep after the next start.
