md2pdf.py:
- Expose --footer and --header (was dead code before)
- Remove --forms flag (B2 fix — weasyprint 68.1 silently drops <input>)
- Substitution support: {page} → counter(page), {pages} → counter(pages)
- Center-aligned via @bottom-center / @top-center
md2doc.py:
- Add --footer and --header support via Word field codes (PAGE, NUMPAGES)
- Center-aligned paragraph in footer/header
- Same {page}/{pages} substitution API as md2pdf
Both tools:
- GFM task list support: - [ ] → ☐, - [x]/- [X] → ☑ (synced _bulletize)
- Help text explains placeholder syntax with examples
