### Purpose Daft Paimon filter conversion previously treated each filter expression as all-or-nothing. For an expression like `A AND unsupported(B)`, the supported conjunct `A` was not pushed to Paimon, so it could not participate in scan planning or file skipping. This PR flattens only `AND` conjuncts in the Daft adapter layer and converts each conjunct independently. Supported conjuncts are combined into a Paimon `AND` predicate, while unsupported conjuncts remain as Daft post-scan filters. `OR` expressions are still pushed only when the whole `OR` is supported. ### Tests - `python3 -m pytest paimon-python/pypaimon/tests/daft/daft_data_test.py paimon-python/pypaimon/tests/daft/daft_explain_test.py -q` -- This is an automated message from the Apache Git Service.
