Description
Is your feature request related to a problem?
We want to support query assistant in cross cluster search. But the final step of query assistant is to execute the PPL, which is not fully supported now. Currently, we need to mock an index locally firstly. https://github.com/opensearch-project/sql/blob/main/docs/user/ppl/admin/cross_cluster_search.rst#limitation
What solution would you like?
A fully supported CCS PPL execution. We don't need to create a mocked index locally.
What alternatives have you considered?
A clear and concise description of any alternative solutions or features you've considered.
Do you have any additional context?

Research direction
Start with docs/user/ppl/admin/cross_cluster_search.rst, especially its documented limitation, and investigate the current PPL execution path for cross-cluster search. Done means PPL executes fully across clusters without requiring a locally mocked index.
