Add model weights to Core NuGet package and publish to GitHub Packages

- Generate default BitNet model weights (.gguf) during CI build and
  include them in the BitNetSharp.Core NuGet package as content files
- Configure both Azure Pipelines and GitHub Actions to publish NuGet
  packages to https://nuget.pkg.github.com/sharpninja/index.json
- Reference McpServer variable library for GH_TOKEN authentication
  in Azure Pipelines
- Add nuget.config with GitHub Packages source and package source
  mapping to prevent dependency confusion
- Bump version to 0.6.0
