lancedb-gatefixer[bot]andXuanwo 913ee160b0 test(python): cover vector index prewarming by name (#3859)
## Summary

- cover vector-index prewarming through the Python API using the logical
index name returned by list_indices
- prevent regression to interpreting a vector index name as a schema
column

## Root cause

The Lance version used by the reported release opened a vector index by
treating the prewarm argument as a column before resolving the index
metadata. Current LanceDB dependencies contain the upstream
metadata-based resolution, but LanceDB only exercised prewarming for FTS
indexes, leaving the vector behavior unguarded.

## Validation

- uv run --extra tests pytest
python/tests/test_index.py::test_create_vector_index -q
- python/.venv/bin/ruff format --check python/python/tests/test_index.py
- python/.venv/bin/ruff check .

Fixes #2897
