feat(arty): generate full Markdown doc in notes command

- New generate_notes_md(): builds title, description blockquote,
  dependencies table, per-script fenced blocks, and details section
  from the entire arty.yml using existing yq helpers
- show_notes() now accepts --raw to print raw Markdown; formatted
  mode pipes through the same glow/mdcat/python3 render pipeline
- Removes the decorative ━━━ border (clashes with full-document output)
- main() passes args[] through to show_notes for flag forwarding
