DescribeMojo.toLines() delegates to generated HelpMojo via fragile reflection

In src/main/java/org/apache/maven/plugins/help/DescribeMojo.java:747-778:

Method m = HelpMojo.class.getDeclaredMethod("toLines", String.class, Integer.TYPE, Integer.TYPE, Integer.TYPE);
m.setAccessible(true);
List output = (List) m.invoke(HelpMojo.class, text, indent, indentSize, lineLength);

HelpMojo is generated by maven-plugin-tools at compile time (in target/generated-sources/). It IS available at runtime, but this reflection is brittle: any change in the generated code toLines signature silently breaks all describe output formatting. The HelpMojo.toLines internally calls repeat() with new StringBuilder(repeat * str.length()) — a classic integer overflow risk that can throw NegativeArraySizeException.

Start in src/main/java/org/apache/maven/plugins/help/DescribeMojo.java:747-778 and inspect the generated HelpMojo.toLines and repeat implementations in target/generated-sources. Verify how describe output formatting is delegated and where integer overflow can occur. Done means describe formatting remains correct without brittle signature dependence or overflow failures.
