Feature request: plugin update status + update mutation (parity with Docker container updates)

[nofuturekid]

Context

Third-party clients (mobile/desktop dashboards, monitoring tools) currently can't tell users when an installed Unraid plugin has a newer .plg version available. The only programmatic install path today is installPlugin(input: InstallPluginInput!): PluginInstallOperation!, which requires the caller to already know the URL of a newer release.

Current schema

type Plugin {
 name: String!
 version: String!
 hasApiModule: Boolean
 hasCliModule: Boolean
}

No latestVersion, no updateAvailable, no equivalent of the Docker update-status surface.

Existing pattern that works well — Docker

The Docker side already solves this cleanly:

enum UpdateStatus { UP_TO_DATE UPDATE_AVAILABLE REBUILD_READY UNKNOWN }
type ExplicitStatusItem { name: String! updateStatus: UpdateStatus! }
type Docker { containerUpdateStatuses: [ExplicitStatusItem!]! }
type DockerMutations {
 updateContainer(id: PrefixedID!): DockerContainer!
 updateAllContainers: [DockerContainer!]!
}

Clients can render a "X updates available" badge and a one-tap update action without scraping registries.

Proposal — mirror for plugins

Either extend Plugin directly:

type Plugin {
 # … existing fields
 latestVersion: String
 updateStatus: UpdateStatus
}

…or add a parallel query field analogous to containerUpdateStatuses:

type Query {
 pluginUpdateStatuses: [ExplicitStatusItem!]!
}

Plus a mutation, reusing the existing PluginInstallOperation tracking:

type UnraidPluginsMutations {
 updatePlugin(name: String!): PluginInstallOperation!
 updateAllPlugins: [PluginInstallOperation!]!
}

Why this matters

Plugin updates today require users to visit Community Applications or each plugin's source URL manually. A schema-level surface unlocks "managed-from-anywhere" parity with the Docker experience the API already provides — and the implementation can reuse the existing .plg re-install path (Unraid's webgui already updates by re-running the .plg from the URL it has).
