Updated project dependencies to include `Microsoft.EntityFrameworkCore.Abstractions` for multiple target frameworks (`net462`, `net7.0`, `net8.0`, `net9.0`). Added `Microsoft.Extensions.*` package references to the project file.
Enhanced `IRepository` interface with methods for executing raw and interpolated SQL queries (`ExecuteSqlRawAsync`, `ExecuteSqlInterpolatedAsync`, etc.). Adjusted method declarations to support conditional compilation for `NET` and `NETFRAMEWORK`.
Refactored namespace structure in `IRepository.cs` to simplify and remove unnecessary conditional compilation directives.
