Name-validation extraction in LtTestNotVerbTest.java not functioning as expected

[0pdd]

The puzzle 872-aad65055 from #872 has to be resolved:

lints/src/test/java/org/eolang/lints/LtTestNotVerbTest.java

Lines 26 to 32 in f9646de

	* @todo #872:60min Extract name-validation logic from LtTestNotVerb into a testable component.
	* Currently {@link LtTestNotVerbTest} parses many EO programs that differ only in the
	* object name being tested, making the tests slow and hard to maintain. The name-validation
	* predicate (verb vs. non-verb check) should be extracted into its own class so it can be
	* tested directly with plain strings — no EO parsing required. Once extracted, reduce
	* {@link LtTestNotVerbTest} to a few representative end-to-end cases and add a dedicated
	* unit test class for the new component.

If you have any technical questions, don't ask me, submit new tickets instead. The task will be "done" when the problem is fixed and the text of the puzzle is removed from the source code. Here is more about PDD and about me.
