Fix: markdownlint MD012/MD019 errors in build-pattern-conversion-plan.md

- Removed extra blank lines at end of file to resolve MD012 (no-multiple-blanks)
- Standardized heading spacing to resolve MD019 (no-multiple-space-atx)
- Stripped trailing whitespace and ensured file ends with a single newline

All changes maintain content integrity and bring the file into full markdownlint compliance.
