Looks good to me except for comments.
- Move test_read_spark_written_puffin_dv from test_puffin_spark_interop.py to test_deletes.py; delete the old file - Replace run_spark_commands helper calls with direct spark.sql() calls - Tighten entries assertion from > 0 to == 1

Rationale for this change
Extracted from #3474 per review feedback (#3474 (comment)): this integration test verifies that PyIceberg can read Puffin deletion vectors written by Spark, which holds independently of the
PuffinWriterchanges in that PR.Are these changes tested?
This PR is test-only. The test passed CI as part of #3474 (integration-test job) before being extracted.
Are there any user-facing changes?
No.
