### Is your feature request related to a problem or challenge? Working with nested list data requires cumbersome unnesting and re-aggregation steps. Native list functions (list_transform, list_filter, and list_reduce) would let users directly operate on list types with concise, expressive syntax, improving both usability and performance. This feature relies on support for lambda functions which is tracked in (https://github.com/apache/datafusion/issues/14205). ### Describe the solution you'd like Implement native list functions that operate directly on nested list types using lambda expressions. For example: `list_transform`: Apply a lambda function to each element in a list. `list_filter`: Filter list elements based on a lambda predicate. `list_reduce`: Aggregate list elements using a lambda function. Note that the lambda function support itself is not available yet; see #14205 for that work. Once lambdas are supported, these list functions can be built on top of them. ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
