fix(ci): handle prerelease versions in AssemblyVersion

AssemblyVersion must be purely numeric (e.g., 1.0.0.0), but dev builds
were passing semantic versions with prerelease suffixes (0.0.0-dev.xxx)
which caused MC1005 build errors.

- Add conditional logic in csproj to allow CI override of AssemblyVersion
- Update ci.yml to pass explicit numeric version for dev builds
- Bump version to 0.6.1
