lancedb-gatefixer[bot] 302b21aa94 test(node): cover nested PDF metadata queries (#3827)
## Summary

- add an end-to-end Node regression matching LangChain PDFLoader
metadata
- verify create/query round trips rich nested `loc` and `pdf.info`
fields against the currently configured Apache Arrow peer

## Root cause

LanceDB v0.14 delegated nested object inference to Apache Arrow. Nested
strings were dictionary-encoded with colliding dictionary IDs, so
serializing query results as an IPC file failed with a
dictionary-replacement error. Current `main` recursively infers nested
fields and avoids those invalid dictionaries, but the reported LangChain
path had no end-to-end regression coverage.

## Validation

- `pnpm build`
- `pnpm lint`
- `pnpm run docs`
- `pnpm test --runInBand` (678 passed, 5 skipped)

Fixes #1963
