v2.0.0 — Theme toggle + multi-format export

First Archify release. Fork / rewrite of Cocoon-AI/architecture-diagram-generator v1.0 (MIT).

Highlights

• Dark / Light theme toggle — one click, persists in localStorage, respects prefers-color-scheme, overridable per-page via ?theme= URL parameter.
• One-click export — PNG, JPEG, WebP (2× retina) and SVG (vector). Works entirely in the browser, no server.
• Keyboard shortcuts — `T` toggles theme, `E` opens Export. Menu supports Arrow / Home / End / Esc / Tab.
• CSS-variable theme system — one SVG markup, two themes.
• Accessibility — full ARIA semantics, keyboard navigation, focus-visible outlines.
