## What changes were proposed in this pull request? ColumnarPartialProject previously did not recognize generic unmapped catalyst expressions shipped in user jars. When such a custom catalyst expression was not registered in `ExpressionMappings`, it was not identified for partial-project fallback and could still reach native expression conversion and fail at runtime. This patch makes Velox detect those generic unmapped catalyst expressions earlier and route them through `ColumnarPartialProject` fallback. `ScalaUDF` and Hive UDF keep using their existing dedicated paths instead of being folded into the generic fallback path. ## How was this patch tested? - Added a Velox unit test with a custom `DummyUnmappedExpr` in `UDFPartialProjectSuite` ## Does this PR introduce _any_ user-facing change? No. ## Was this patch authored or co-authored using generative AI tooling? Yes. Generated-by: OpenAI GPT-5 -- This is an automated message from the Apache Git Service.
