# Which issue does this PR close?
Adds `PutMultipartOptions` support to the low-level `MultipartStore` create
flow via a new `create_multipart_opts` method.
This is implemented for AWS, GCP, in-memory, and wrapper stores. Azure
returns `NotSupported` for non-default tags/attributes because Azure applies
these options when finalizing block uploads, not when creating them. Supporting
this in the low-level API would require local upload state, which could leak if
uploads are never completed or aborted.
Closes #745

# What changes are included in this PR?
<!--
There is no need to duplicate the description in the issue here but it is
sometimes worth providing a summary of the individual changes in this PR.
-->
* Adds `MultipartStore::create_multipart_opts`
* For AWS/GCP, passes options through to the backend client
* For `PrefixStore`/`ThrottledStore`, delegates options to the wrapped
multipart store
* For in-memory, stores attributes in `PartStorage` until completion
* For Azure, returns `NotSupported` for non-default tags/attributes
# Are there any user-facing changes?
<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->
Yes. `MultipartStore` has a new default method, `create_multipart_opts`, so
existing implementations remain source-compatible.
<!---
If there are any breaking changes to public APIs, please call them out.
-->
There are no breaking changes to the public API; the new method has a
default implementation.
