Binary release builds fixed (NETSDK1207)

Build-only fix: the release pipeline's binary build jobs were failing for all targets (Linux, macOS, Windows). No user-facing output changes.

🐛 Bug fixes

Binary release builds failed with NETSDK1207: PublishAot=true was propagating from the main Oocx.TfPlan2Md project into the JsonEmbedGenerator analyzer project reference during dotnet publish. Because JsonEmbedGenerator targets netstandard2.0, the .NET SDK rejected the AOT property with NETSDK1207: Ahead-of-time compilation is not supported for the target framework. All binary targets (linux-x64, linux-musl-x64, osx-x64, osx-arm64, win-x64) were blocked. The fix marks the analyzer project reference as AOT-isolated via GlobalPropertiesToRemove on the ProjectReference and adds TreatAsLocalProperty="PublishAot" + <PublishAot>false</PublishAot> in the generator project to prevent restore-time propagation.
