   # Which issue does this PR close?
   
   Closes # https://github.com/apache/auron/issues/2126
   
   # Rationale for this change
   Spark Acosh expressions were not wired into Auron’s standard builtin scalar 
function conversion path, so acosh(expr) could not be planned through the 
native backend.
   
   This change follows the existing ScalarFunction flow used by other builtin 
math functions such as acos, asin, and atan: Spark expression conversion in 
NativeConverters, protobuf enum registration in auron.proto, and planner 
mapping in planner.rs. This keeps acosh aligned with the current architecture 
instead of introducing a custom extension function path.
