chore: update lance dependency to v8.0.0-rc.2

fix(python): route async namespace connections through rust (#3603 )
Summary: - Route built-in async namespace-backed connections through the Rust namespace connector. - Delegate async namespace/table management methods to the inner AsyncConnection while keeping the custom implementation Python-client fallback. - Add regressions for the native async dir path and lazy namespace_client() construction. Validated locally with targeted namespace/db/table pytest, full test_namespace.py, ruff, cargo fmt/check/clippy, and cargo test -p lancedb-python.
