### Is your feature request related to a problem or challenge? #17988 introduced `percentile_cont()`. If the specified percentile is 0 or 1, we could rewrite the function to use min/max instead which would be equivalent but with lower memory usage (`percentile_cont()` by default buffers entire input). ### Describe the solution you'd like Implement `simplify()` for `percentile_cont`, based on if fraction is a provided literal that is 0 or 1, rewriting to min/max. Things to consider: - Consider sort order (percentile of 0 ascending = min, but percentile of 0 descending = max) - Ensure return types match See this comment for reference: https://github.com/apache/datafusion/pull/17988#discussion_r2429329576 ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
