Walkthrough

The frontend now sends sibling and child IDs as comma-separated strings. OrgChart converts these strings to JsonArray values before invoking the existing event-processing logic.

Changes

Mutation callback compatibility

Layer / File(s)	Summary
Client ID transport src/main/resources/META-INF/frontend/fc-orgchart.js	Sibling and child callbacks now send comma-separated ID strings.
Server callback conversion src/main/java/com/flowingcode/vaadin/addons/orgchart/OrgChart.java	OrgChart handles string callback parameters, converts IDs to JsonArray values, and delegates to the existing handlers.
