Research direction

Start by inspecting SemanticTokensInspectorManager.java at doFormat line 92 and LSPIJUtils.java at applyEdit line 1002, following the stack trace to the invalid offset calculation. Reproduce the semantic-token inspector formatting case that produces the exception and verify that formatting no longer attempts an offset beyond the document length.
