fix: improve plugins functionality with server management

@@ -81,6 +81,8 @@ The renderer sends structured command/query objects through the Electron preload
 
 The Electron schema now normalises reaction rows and room channel/member rosters into separate SQLite tables instead of storing those arrays inline on the parent message or room rows. The renderer-facing API is unchanged: CQRS handlers rehydrate the same `Message` and `Room` payloads before returning them over IPC.
 
+Electron room membership is user-scoped through `room_owners`, and messages carry `ownerUserId`. Auth setup writes the current user ID to the database before room loading, so `/search`, the server rail, and local history only hydrate rooms/messages owned by the active account. A room row can still hold shared server metadata for the same server ID, but each account has its own ownership edge and message history.
