## Summary This PR adds unit tests to verify that `StringView` and `BinaryView` arrays are correctly compacted (garbage collected) before being spilled to disk. The tests address [Issue #21683](https://github.com/apache/datafusion/issues/21683) by: 1. Creating "bloated" batches with large underlying buffers. 2. Slicing them to a small number of rows (1%). 3. Spilling them to disk. 4. Asserting that the resulting file size is small (proving that GC removed the unused "ghost" data). ## Test plan - Run `cargo test -p datafusion-physical-plan --lib spill::mod::tests::test_spill_file_size_gc_verification_string_view` - Run `cargo test -p datafusion-physical-plan --lib spill::mod::tests::test_spill_file_size_gc_verification_binary_view` Made with [Cursor](https://cursor.com) -- This is an automated message from the Apache Git Service.
