ci(nuget): allow auto or explicit package version in workflow (#440)

Add flexible version management to NuGet workflow:
- New `version` input parameter with default "latest" for workflow
dispatch
- Auto-generate date-based version (yyyy.MM.dd.0) when "latest" is
specified
- Validate version format follows X.Y.Z.W pattern
- Dynamically set package version in .csproj before building

This enables both automatic versioning and explicit version control.
