Upgrade library, test project, and CI workflows to .NET 10

[Copilot]

This updates the repository from .NET 9 to .NET 10 across the project, build pipeline, and package metadata. It also aligns direct development dependencies with the new target and removes a framework package reference that is no longer needed under .NET 10.

• Framework targeting

  • Retargets the library and test projects from net9.0 to net10.0

• Package/dependency updates

  • Updates direct package references used for packaging and test infrastructure
  • Removes the explicit Microsoft.Extensions.DependencyInjection reference, which is implicitly available for this project type on .NET 10

• CI/release pipeline

  • Updates GitHub Actions workflows to install and build with .NET 10.x

• Documentation

  • Adds a brief README note that current builds and package development target .NET 10

<TargetFramework>net10.0</TargetFramework>

• Fixes Update Project to .NET 10 #108
