- Implements Phases 3–6: session isolation, cache coordination, primary election, and file system monitor coordination for Jellyfin with PostgreSQL. - Adds new database entities (Instance, DistributedLock, FileSystemChange) and EF model configurations. - Includes SQL migration scripts and EF migration for all required tables, columns, and helper functions. - Updates Device entity and JellyfinDbContext for multi-instance tracking. - Integrates new DI services for instance registry, distributed locks, cache coordinator, and primary election. - Adds publishing profiles (Win/Linux/FrameworkDependent) and automation script for deployment. - Extensive documentation for architecture, setup, and publishing. - All changes are backward compatible and build successfully.
