Upgraded the target framework for all main, test, and provider projects from .NET 10.0 (net10.0) to .NET 11.0 (net11.0). Updated all major NuGet dependencies to their .NET 11-compatible versions, including Microsoft.AspNetCore.*, Microsoft.EntityFrameworkCore.*, Microsoft.Extensions.*, Serilog, System.Text.Json, and Npgsql.EntityFrameworkCore.PostgreSQL (now 11.0.0-preview.1). Regenerated all project.assets.json, NuGet cache, and MSBuild files to reflect the new framework and package versions. Removed or updated incompatible dependencies and references. Set allWarningsAsErrors: true in NuGet spec files for stricter builds. No application logic changes were made; all updates are related to project configuration, dependency management, and build system modernization for .NET 11.0.
Introduce Jellyfin.Database.Providers.Postgres project, enabling PostgreSQL as a database backend using Entity Framework Core 10 and Npgsql. Add custom value converters and model builder extensions for PostgreSQL compatibility. Update solution-wide dependencies to Microsoft.EntityFrameworkCore 10.0.3 and Npgsql.EntityFrameworkCore.PostgreSQL 9.0.2 (as a temporary workaround until 10.x is released). Regenerate all relevant NuGet, build, and cache files. Add new and updated binaries, debug symbols, and XML documentation for affected projects. No application source code changes outside of the new provider and supporting infrastructure.
