/**
 * Plugin update check endpoint
 *
 * GET /_emdash/api/admin/plugins/updates - Check for available updates
 * across every installed plugin source (marketplace + experimental
 * registry). Items are returned in a single flat list; admins correlate
 * items to plugins by `pluginId` and read `source` from the existing
 * `/_emdash/api/admin/plugins` list (the pluginId prefix is not a
 * reliable discriminator on its own).
 *
 * A failure in one source does NOT blank the other — a registry-side
 * aggregator outage still returns marketplace updates and vice versa.
