Add release workflow and update NuGet package metadata (#1)

## Summary

- Added a GitHub Actions workflow (`.github/workflows/release.yml`) to
automate building, testing, packaging, and publishing releases to GitHub
Packages when a `v*` tag is pushed. Also creates a GitHub Release with
generated release notes.
- Added `RepositoryUrl`, `PackageProjectUrl`, and `RepositoryType` to
`DotLuxafor.csproj` for better NuGet package traceability.
- Increased timeouts in flaky hosted service tests to reduce CI timing
failures on slow runners.
