lancedb-gatefixer[bot] ec21e37040 test(rust): cover Hugging Face table symlinks (#3887)
## Summary

- cover Hugging Face cache layouts where both manifests and Lance data
files are relative symlinks into a blob directory
- reconnect with a fresh session before opening so the test exercises
filesystem discovery instead of cached manifest metadata
- scan the reopened table to verify both manifest recovery and data-file
reads

## Root cause

Lance 3.0.1 recorded Unix symlink metadata as the known manifest size,
so the short link length caused a file size is too small error. The
current Lance v11.0.0-beta.2 dependency repairs this by detecting an
invalid footer from a stale known size and retrying with the target file
metadata. This regression test locks that behavior into the LanceDB
open-table path used by Node.

## Validation

- cargo fmt --all
- cargo test --quiet --features remote -p lancedb --lib
test_open_table_follows_hugging_face_symlinks -- --nocapture
- cargo test --quiet --features remote -p lancedb --lib
database::listing::tests
- cargo clippy --quiet --features remote -p lancedb --lib --tests -- -D
warnings
- cargo check --quiet --features remote --tests --examples

Fixes #3197
