### Rationale for this change The `SparseCSFIndex::Equals` method lacks bounds checking when comparing two indices with different dimensions. This leads to out-of-bounds access and a segmentation fault. ### What changes are included in this PR? - Added size equality checks for `indices()` and `indptr()` vectors at the beginning of `SparseCSFIndex::Equals`. ### Are these changes tested? These are simple size checks that prevent out-of-bounds access. Manual verification confirms that comparing indices with different sizes will now correctly return `false` instead of crashing. ### Are there any user-facing changes? No, except that the code no longer crashes in this specific edge case. -- This is an automated message from the Apache Git Service.
