lancedb-gatefixer[bot] 9d3962686e fix(node): accept Arrow metadata across JavaScript realms (#3904 )

## Summary

- accept genuine Arrow metadata maps created in another JavaScript realm
- validate every metadata entry and clone it into a local Map
- cover an Arrow 15 VM-realm table through the public fromDataToBuffer
boundary
- retain structural typing for nested and dictionary Arrow data

## Root cause

The sanitizer used a local-realm instanceof Map check for schema and
field metadata. A genuine Map created in another JavaScript realm has
the required internal Map state but fails that identity check, so
fromDataToBuffer rejected the foreign table before serializing its rows.

## Scope

This fixes the distinct JavaScript-realm sanitizer failure identified
during review. It does not establish the cause of the S3/compaction
panic reported in #1525, so that issue remains open.

## Validation

- pnpm test --runInBand (707 passed, 5 skipped)
- pnpm test --runInBand __test__/arrow.test.ts (189 passed)
- pnpm build
- pnpm lint
- pnpm run docs
