Will Jones 5d3f06c44a test: update hash-split expectations for DataFusion 54 foldhash
DataFusion 54's `create_hashes` uses foldhash instead of ahash, so the
concrete hash values (and therefore split assignments) differ from the
DF53 baseline:

- `test_hash_split` (Rust): recompute the expected per-split counts.
- `test_split_hash_with_discard` (Python): hash a high-cardinality
  column instead of the 2-value `category`, so the discard ratio no
  longer hinges on where two specific hashes land.
