VictorECDSA ff5971448b [Fix] naive: force-merge short markdown headers to prevent separate chunks (#15488) ...

## Problem

When uploading `.md` files with `parser=naive` and `delimiter="\n"`,
markdown headers (e.g., `## Quick Travel`) become separate chunks with
very short content (16-18 characters). This causes retrieval issues:
when the header is matched, the corresponding body text is not included
in the chunk.

## Related Issues

Closes #15487

## Checklist

- [x] Code changes are minimal and focused
- [x] Unit tests added (12/12 passed)
- [x] No breaking changes
