Update Workflow Diagram from Mermaid

Purpose

Regenerate the website/ai-workflow.svg file from the canonical mermaid diagram in docs/agents.md. The website uses a hand-crafted blueprint-styled SVG that preserves the exact layout generated by mermaid but applies a custom visual style (technical drawing aesthetic with cyan/white on dark blue).

When to Use

• After changes to the mermaid diagram in docs/agents.md
• When adding, removing, or renaming agents/artifacts
• When modifying the workflow connections

Hard Rules

Must

• Use mermaid-cli (mmdc) to render the mermaid diagram to SVG
• Parse the generated SVG to extract node positions and path definitions
• Preserve exact node positions and path routing from mermaid output
• Apply blueprint styling consistently per node type
• Keep the SVG self-contained (all styles inline or in <style> block)
