lancedb-gatefixer[bot] 607e556927 test(python): cover search after schema merge (#3784) ...

## Summary

- add an end-to-end regression for indexed vector search after merging a
pandas column
- verify unmatched rows retain a null merged value instead of failing
Arrow batch assembly

## Root cause

Historical Lance readers could assemble schema-evolved columns in
physical data-file order. Indexed row-ID reads after a merge could
therefore omit or misorder the newly merged column for unmatched rows.
The currently pinned Lance release contains the reader correction, but
LanceDB did not cover the reported merge-then-search path.

## Validation

- uv run --extra tests pytest python/tests/test_table.py::test_merge
python/tests/test_table.py::test_search_after_merge -q
- uv run --project python --extra dev ruff check .
- uv run --project python --extra dev ruff format --check
python/python/tests/test_table.py

Fixes #599
