## Which issue does this PR close? Backport of #6829 to `branch-1.1`. ## Rationale for this change Comet's approximate-percentile ordering did not match Spark for negative NaNs. This can produce different percentile results for the same input and should be corrected in the 1.1 release line. ## What changes are included in this PR? Cherry-picks #6829 with `-x`. The native quantile summary now follows Java primitive-array ordering for non-finite values, and the SQL regression coverage exercises NaN sign and payload behavior. No branch-specific adaptation was required. ## How are these changes tested? Ran: ```text cd native cargo test -p datafusion-comet-spark-expr quantile_summaries --lib ``` Result: 15 quantile-summary tests passed. -- This is an automated message from the Apache Git Service.
