0.1.0

Initial release.

• NodeFlow<T, E> canvas widget: infinite pan/zoom viewport, dotted background grid, app-defined node visuals via nodeBuilder.
• FlowController<T, E>: nodes, edges, selection, marquee, viewport operations (fitView, zoomTo, centerOnNode), and callback seams for app-owned undo/persistence (onMoveCommitted, onDeleted, onEdgesDeleted).
• Node dragging with multi-selection, locked nodes, grid snap on commit, and Figma-style alignment snap guides.
• Ports and drag-to-connect with compatible-port detection, connection preview, and normalized onConnect requests.
• Edge styles: bezier, smoothstep, and straight, with optional animated flowing-dash rendering, hit-testing, and selection.
• Pannable minimap overlay with viewport indicator.
• Zero-dependency theming: explicit FlowTheme, ThemeData extension lookup, or built-in dark defaults.
