Add test cases for new collection factory methods

[Copilot]

Adds comprehensive unit test coverage for newly generated factory methods across all collection utility classes. Tests validate creation, initialization, type correctness, and element handling for thread-safe and specialized collection types.

Test Coverage by Utility Class

SetUtils (5 tests)

• CopyOnWriteArraySet creation with/without collection argument
• ConcurrentSkipListSet creation variants with collection and sorted set arguments

ListUtils (2 tests)

• CopyOnWriteArrayList creation with/without collection argument

QueueUtils (17 tests)

• PriorityQueue with capacity, comparator, and collection initialization
• ConcurrentLinkedQueue variants
• LinkedBlockingQueue with capacity and collection arguments
• ArrayBlockingQueue with capacity and collection arguments
• PriorityBlockingQueue initialization
• DelayQueue, SynchronousQueue, and LinkedTransferQueue creation

MapUtils (8 tests)

• ConcurrentSkipListMap creation and ordering verification
• WeakHashMap with capacity and map initialization
• IdentityHashMap with expected size and map initialization

PropertiesUtils (2 tests)

• Properties creation with and without default values

Example Test

@Test
void testNewConcurrentSkipListSetWithCollection() {
    Collection<String> source = asList("c", "a", "b");
    ConcurrentSkipListSet<String> set = newConcurrentSkipListSet(source);
    assertEquals(3, set.size());
    // Verifies sorted order maintained by concurrent skip list
    Object[] elements = set.toArray();
    assertEquals("a", elements[0]);
    assertEquals("b", elements[1]);
    assertEquals("c", elements[2]);
}

Total: 34 new test cases ensuring factory method correctness and thread-safety properties.
