bitloi 9f3e289b78 Fix: preserve markdown tables during delimiter extraction (#15632) ...

### What problem does this PR solve?

Markdown extraction can split tables row by row when delimiter-based
extraction uses a newline delimiter. That loses table structure during
chunking even though delimiters should still split normally outside
tables.

This PR keeps the follow-up to #15482 intentionally narrow:

- preserve Markdown pipe tables during delimiter-based extraction
- preserve borderless pipe tables during delimiter-based extraction
- preserve multiline HTML tables during delimiter-based extraction
- keep delimiter splitting unchanged outside protected table ranges

Refs #15482
