Subject: [PATCH 4/5] Remove redundant net9.0 and net10.0 buildTransitive
 folders

The net8.0 buildTransitive folder is automatically selected by NuGet for net9.0 and net10.0
through nearest compatible framework selection. Only the target name fix was needed.

Subject: [PATCH 5/5] Use generic buildTransitive files for all TFMs

Instead of TFM-specific folders (net6.0, net8.0, net9.0, net10.0), use generic
buildTransitive files that apply to all target frameworks. This prevents the issue
where NuGet's framework selection doesn't automatically apply net8.0 files to net9.0.

- Moved buildTransitive files to root of buildTransitive folder (no TFM subfolder)
- Disabled automatic TFM-specific buildTransitive generation via DisableNETStandardCompatErrors
- Updated packaging to only include root-level buildTransitive files
