### Describe the bug `cardinality()` returns incorrect results for ragged nested arrays. For nested arrays, `cardinality()` should count the total number of leaf elements. However, the current implementation computes array dimensions using the first child array and then multiplies those dimensions. This works for rectangular nested arrays, but gives incorrect results for ragged nested arrays. ### To Reproduce ```sql SELECT cardinality([[1], [2, 3]]); ``` Current result: 2 Expected result: 3 ### Expected behavior _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
