Added a new `ECMJobRunner.Tests` project to the solution for unit
testing, including build configurations for Debug and Release.
Enhanced the `DependencyExtension` class to support dependency
injection for both .NET Framework 4.8 (EF6) and .NET 8 (EF Core)
using conditional compilation. Registered `JobRunnerDbContext`
differently based on the target framework and added AutoMapper
registration for both frameworks.
Updated `ECMJobRunner.Infrastructure.csproj` to include new
package references for DI and AutoMapper in .NET Framework 4.8.
Improved code structure and readability by removing redundant
directives and aligning DI patterns across frameworks.
Introduced a robust Infrastructure layer for the ECMJobRunner system:
- Added `AGENTS.md` with detailed project documentation.
- Implemented generic repository and unit-of-work patterns.
- Added `CfgProfileRepository`, `ProfileSqlJobRepository`, and `ProfileHistoryRepository`.
- Integrated AutoMapper for DTO-to-entity mapping.
- Added multi-framework support for .NET Framework 4.8 (EF6) and .NET 8.0 (EF Core) using conditional compilation.
- Updated `ECMJobRunner.Infrastructure.csproj` with metadata fixes and dependencies.
- Introduced dependency injection extension for .NET 8.0.
- Enhanced project structure and database context with entity mappings.
