v0.2.0

What's Changed

This release upgrades the underlying renderer from ariel-rs 0.1.0 → 0.4.0, picking up three releases worth of fixes, theme work, and a new fidelity-testing mode.

📦 Dependency Upgrade

• ariel-rs: 0.1.0 → 0.4.0

That's a big jump — here's what it brings to arielc:

From ariel-rs 0.2.0

• Full 4-theme support (Default, Dark, Forest, Neutral) with pixel-accurate colors across 28+ diagram types
• Theme-aware fixes in sequence, flowchart, class, state, ER, gantt, git, block, treemap, kanban, packet, sankey, radar, timeline, C4, architecture, ishikawa, wardley, mindmap, pie, venn
• TreeView diagram support

From ariel-rs 0.3.0

• ER self-loop arcs match Mermaid JS exactly
• Pure SVG output — no <foreignObject>, rasterizable by any tool (resvg, librsvg, Inkscape)
• Treemap / block dark-theme label colors corrected

From ariel-rs 0.4.0

• Renderer-wide theme externalization (font family now flows from ThemeVars through every template)
• Templates refactor (all inline SVG strings centralized)
• Class diagram namespace + note layout corrected to match Mermaid's adjustClustersAndEdges
• Flowchart hexagon padding + bidirectional edge fixes
• Sequence viewBox formula matches Mermaid
• Kanban section-2 white-on-purple header (default theme)
• Mindmap layout switched to recursive subtree-height algorithm
• Text rendering switched to Mermaid's tspan-with-dy pattern across all renderers

✅ Verification

• All 12 CLI integration tests pass
• All 4 themes render correctly (default, dark, forest, neutral)
• All supported diagram types render
