Summary

The 7.3.2 release failed before publishing anything. Two bug-hunt fixes tripped the trim analyzers, which the NativeAOT publishes turn on for ExcelReader.Core with warnings as errors.

 SyncRowEnumerator.Box(T value)        // E5, non-generic IEnumerator.Current
-  RuntimeHelpers.GetUninitializedObject(typeof(T)) + raw write   // IL2087: needs ctor annotations on T
+  RuntimeHelpers.Box(ref Unsafe.As<T, byte>(ref value), typeof(T).TypeHandle)

 SheetDataReader.GetFieldType -> TypeOf(cell)   // E2
+  [return: DynamicallyAccessedMembers(PublicFields | PublicProperties)] on TypeOf   // IL2073

RuntimeHelpers.Box also boxes Nullable<T> correctly, which the raw write did not guarantee.

Evidence

• Before: dotnet build src/ExcelReader.Core -c Release -p:EnableTrimAnalyzer=true -p:EnableAotAnalyzer=true fails with IL2087 (SyncRowEnumerator.cs:60) and IL2073 (SheetDataReader.cs:208), the same two errors as the release job.
  After: 0 errors. python python/scripts/build_native.py (the step that failed) publishes ExcelReader.Native.dll with no IL warnings. Test suite: 4020 / 4020.

Merge Danger

Door: two-way. Two internal edits, with no public API or behavior change.

Blast Radius: none.

After merge, v7.3.2 is re-tagged on the merge commit and the release re-runs. Nothing from the failed run reached NuGet, PyPI or crates.io.
