Commit Message

Fix to_bjdata() silently truncating out-of-range _ArrayData_ elements (#5473)

write_bjdata_ndarray() validated that each _ArrayData_ element matched
the number kind (integer vs. float) named by _ArrayType_, but not its
range. An element that did not fit the target C++ type (e.g. 256 for
"uint8") was silently wrapped by the static_cast used to write it, or,
for "single", silently overflowed to infinity.

Range-check each element against the type named by _ArrayType_ before
writing it, reusing the existing fallback path that already encodes
the annotated object as a plain object for other invalid-annotation
cases in this function.

Fixes #5403.
