v1.0.1

Fixed

• graph Mermaid output now assigns each node a collision-free identifier. Distinct node ids
  that sanitized to the same Mermaid-safe token previously merged into one graph node.
• Heading anchor parsing now recognizes {#marker} only as a trailing heading marker
  (optionally followed by an ATX closing # sequence). An anchor-like token in the middle of
  heading text is no longer mistaken for the heading's explicit anchor.
