v2.2.0 — Mermaid input + deterministic layout engine

Feature release — paste a Mermaid source (or describe a system in plain English) and get the same animated, self-contained HTML diagram.

Highlights

• Mermaid input — flowchart / graph / stateDiagram-v2 → an animated diagram. Every node, edge, edge label and subgraph containment is preserved; layout is recomputed top-down. Unsupported diagram types are declined rather than lossily guessed.
• Deterministic layout engine (scripts/layout.py, pure stdlib) — the model emits a semantic graph, the script computes all geometry (routing, boundaries, journeys). Large diagrams generate dramatically faster, with zero structural violations.
• Mechanized self-check — bundled check_diagram.py (structure) and check_fidelity.py (Mermaid labels/edges verbatim) run at generation time and fix what they find.

The output stays dependency-free: one self-contained HTML file — no libraries, no build step.
