lancedb-gatefixer[bot] 5153e5a023 fix(node): preserve JSON field metadata when adding data (#4064 )

## Summary

- preserve Arrow field metadata when matching record data to a provided
schema
- retain metadata on partially reconstructed nested struct fields
- add a regression test for lance.json metadata through Arrow IPC
serialization

## Root cause

The TypeScript schema inferrer rebuilt fields selected from a provided
schema without copying their metadata. JSON columns therefore kept their
LargeBinary physical type but lost the lance.json extension marker
before insert, causing the schema mismatch reported in the issue.

## Validation

- pnpm lint
- pnpm build
- pnpm tsc
- pnpm run docs
- pnpm test --runInBand (18 suites and 798 tests passed; 5 tests
skipped)

Fixes #4062
