fix: resolve all CI and versioning issues in one pass

- Remove hardcoded <Version>1.0.0</Version> from csproj (moved to Directory.Build.props)
- Remove <GeneratePackageOnBuild>true</GeneratePackageOnBuild> to prevent duplicate packing
- Add .NET 10 SDK to publish workflow (project targets net10.0)
- Restore push-to-nuget toggle for flexible publish/dry-run
