dennis zhuang bb9b7e8778 fix: re-scan stream-backed tables in recursive CTEs (#9039 )

* fix: re-scan stream-backed tables in recursive CTEs

A recursive CTE re-executes its recursive term on every iteration, but
DfTableProviderAdapter hands StreamScanAdapter a single-use stream built at
planning time. The second iteration failed with "Stream already exhausted"
for every table served through DataSource::get_stream — information_schema,
pg_catalog, the computed entity-graph tables and numbers.

Keep that stream for the first execution and open a new one over the same
scan request for later executions.

Closes #9037
