+//! Plugin Data entity for system-scoped (per-plugin) key-value storage.
+//!
+//! Mirrors [`super::user_plugin_data`] but is keyed by `plugin_id` rather than
+//! `user_plugin_id`. System plugins (e.g. release sources) run with no user
+//! context, so they can't use the per-user store; this is their durable KV
+//! bucket — used, for example, to persist a release feed cursor.
+//!
+//! ## Storage Isolation
+//!
+//! Each entry is scoped to a specific `plugin_id`. Plugins can only address
+//! their own data by key; the host resolves the plugin scope from the
+//! connection context.
+//!
+//! ## TTL Support
+//!
+//! Entries can optionally have an `expires_at` timestamp for cached data. A
+//! background cleanup task removes expired entries periodically.
