test: Implement automated unit tests for core components

[Copilot]

Implemented comprehensive unit test coverage for the core components of the NetEvolve.ForgingBlazor project, focusing on ApplicationBuilder, ServiceCollectionExtensions, and ApplicationBuilderExtensions. This ensures robust validation of the framework's foundational logic and helps prevent regressions.

Changes Made

• ApplicationBuilderTests (19 tests): Covers constructors, factory methods (CreateDefaultBuilder, CreateDefaultBuilder, CreateEmptyBuilder), Build method, and validation logic
• ServiceCollectionExtensionsTests (14 tests): Covers AddForgingBlazorServices, AddMarkdownServices, and IsServiceTypeRegistered helper method
• ApplicationBuilderExtensionsTests (19 tests): Covers AddDefaultContent, AddDefaultContent, AddSegment, and AddBlogSegment with both generic and non-generic overloads

Test Coverage

• ✅ All public methods in ApplicationBuilder and ServiceCollectionExtensions tested
• ✅ Typical usage scenarios covered
• ✅ Edge cases tested (null arguments, empty collections, etc.)
• ✅ Exception handling validated (ArgumentNullException, InvalidOperationException)
• ✅ Service registration and builder pattern functionality verified
• ✅ Tests follow TUnit framework patterns and C# coding conventions

Testing

• ✅ All 126 tests passing on both .NET 9.0 and .NET 10.0
• ✅ Code review completed with no issues
• ✅ Security scan found zero vulnerabilities
• ✅ Tests are integrated into the CI pipeline and run automatically

The implementation fulfills all acceptance criteria from the original issue, providing comprehensive test coverage that will help maintain code quality and prevent regressions as the codebase evolves.
