feat(python): add CombinedFieldsQuery for BM25F full text search

Browse Source 
Add a typed Python `CombinedFieldsQuery` for BM25F search across multiple columns.

The query mirrors Lance's combined-fields semantics with ordered per-column boosts and AND/OR term matching. Convert it in both directions at the PyO3 boundary, including nested Boolean queries, and document the Python typed convenience entry.

Closes #4652.
