fix: NuGet symbols package publishing failure

- IO csproj: remove DependsOnTargets="Build" from PackSourceGenerator target,
  use $(MSBuildThisFileDirectory) for reliable path resolution
- SG csproj: add IsPackable=false to prevent source generator from being
  published as standalone NuGet package
- CI: clean bin/obj before scanning, limit to ./src, drop deprecated
  --include-source flag, merge nupkg+snupkg push into single atomic call
