Upgrade to release 26.6.1:
- Bump vendored FlatBuffers from v25.9.23 to v25.12.19, restoring
the version-sync with zlmdb 26.6.1
- Commit the binary schemas (reflection.bfbs, wamp.bfbs) to the source
tree and ship them as-is; the package build no longer runs flatc,
which fixes cross-compilation from the PyPI sdist
(e.g. Buildroot/Yocto/aarch64)
- Add just generate-reflection to regenerate the committed binary
schemas with a version-matched flatc built from deps/flatbuffers
- Add just check-flatbuffers-sync and a unit test exercising
check_zlmdb_flatbuffers_version_in_sync()
