✨ Upgrade to Docusaurus 3, Embed preview of .xircuits workflows

[MFA-X-AI]

Description

Adds xircuits-graph-viewer - a standalone, pure SVG renderer for .xircuits workflow files. It parses the .xircuits JSON format and produces self-contained SVG that visually matches the Xircuits editor, including title bar gradients (oklch), port symbols, flow/data bezier edges, comment nodes, and the actual Xircuits node icons.

Published to npm as:

• @xpressai/xircuits-viewer - core parser + renderer, zero runtime deps
• @xpressai/xircuits-viewer-react - React components with src prop (pass a URL, it renders)

Includes:

• Core package: parser, layout engine, SVG renderer, pan/zoom interaction, dark/light theme support
• React package: <XircuitsGraph> (interactive) and <XircuitsGraphStatic> (SSR-safe) components
• Upload demo: standalone Vite app - drag-and-drop any .xircuits file to view it
• Docusaurus docs site: workflow documentation pages with interactive viewer, floating zoom controls, loading states, and theme sync
• 24 tests covering parser and renderer
• Publish script (publish.sh) for npm releases

Tests

24 unit tests covering parser and renderer.

1. Parser tests (11)

1. cd xircuits-graph-viewer
2. node_modules/.bin/vitest run
3. Validates .xircuits files, parses nodes/ports/edges, classifies node kinds (start, finish, literal, component, comment)

2. Render tests (13)

1. Verifies SVG output contains correct elements, gradients, styles, node names, port symbols, edge types
2. Tests dark and light theme rendering
3. Tests node metrics computation for component, comment, and literal nodes

3. Manual testing

1. Upload demo: drag-and-drop HelloXircuits.xircuits, ControlflowExample.xircuits - verify rendering, pan/zoom, theme toggle
2. Docusaurus site: npm start, verify workflow pages render with interactive viewer
