chore(deps): bump packages and upgrade to .NET 8.0

- Upgrade target frameworks from net6.0 (EOL) to net8.0 for security updates
- Bump direct dependencies to latest:
  - Devlooped.Web 1.2.0 -> 1.4.0
  - DotNetConfig 1.0.6 -> 1.2.0
  - Microsoft.CodeAnalysis.CSharp.Scripting 4.6.0 -> 5.3.0
  - Microsoft.SourceLink.GitHub 10.0.202 -> 10.0.300
  - Microsoft.NET.Test.Sdk 17.13.0 -> 18.7.0
  - Moq 4.18.4 -> 4.20.72
  - xunit.runner.visualstudio 3.0.2 -> 3.1.5
- Update ThisAssembly usage for v2 (split packages to avoid resource generator issues with 'default.md')
- Updated local dev pin in Directory.targets

All tests pass (171/171).
