Cloud Storage

Integrates with Firebase for cloud persistence and file storage. Unlike AI services, SvFirebaseService extends SvSummaryNode directly and contains two sub-services:

• SvFirestoreDatabaseService — Document and collection access via Firestore. Provides query building, real-time listeners, and CRUD operations through Strvct node wrappers (SvFirestoreNode, SvFirestoreQuery).
• SvFirebaseStorageService — File upload and download via Firebase Storage, with permission management.
