Issue #105: GetIterator trait was not implemented and threw RuntimeException.

Implementation:
- Implement getIterator(): \Traversable delegating to $this->collection
- Return type \Traversable<array-key, mixed>
- Remove RuntimeException placeholder
- Clean unused imports

Tests added:
- testGetIteratorReturnsTraversable
- testGetIteratorAllowsForeach
- testGetIteratorWithEmptyCollection
- testGetIteratorPreservesKeys
- testGetIteratorWithNestedArrays

Fixes #105

CI tests were failing because manual foreach loops weren't correctly
capturing iterator values. Use iterator_to_array() for reliable iteration testing.
