+/**
+ * Render graphviz diagrams from a skill's SKILL.md to SVG files.
+ *
+ * Usage:
+ *   ./render-graphs.js <skill-directory>           # Render each diagram separately
+ *   ./render-graphs.js <skill-directory> --combine # Combine all into one diagram
+ *
+ * Extracts all ```dot blocks from SKILL.md and renders to SVG.
+ * Useful for helping your human partner visualize the process flows.
+ *
+ * Requires: graphviz (dot) installed on system
