Change log in 2025.12.26:

• More Free Publish Callback: Users can now choose to return publish_ok or publish_error in the publish callback, instead of the previously enforced publish_ok.
• Stream Reuse: Added support for sending multiple objects over a single QUIC stream (using the same subgroup/group ID). previously, a separate subgroup/group was used for each object. This feature is enabled via xqc_moq_track_set_reuse_subgroup_stream.

You can test by moq_scripts/moq_case_test_v14.sh .
