Reviewer's Guide

This PR reverts parts of a previous change by simplifying several catch blocks: it removes unused exception variable bindings while preserving the existing error-handling behavior across tests, task handling, server operations, HTTP responses, and exchange/shuffle operators.

File-Level Changes

Change	Details	Files
Remove unused exception variable names from catch blocks while preserving existing error-handling behavior.	In test code, catch VeloxUserError by type only and fall back to parsing string values without inspecting the exception. In task creation/update logic, catch VeloxException and VeloxUserError by type only, still rethrowing or wrapping as before. In server operations and HTTP response helpers, catch std::exception by type without using the exception instance, keeping the same failure paths and messages. In broadcast and shuffle exchange/write components, catch VeloxException by type and rethrow, leaving downstream error conversion to existing handlers.	presto-native-execution/presto_cpp/main/tests/PrestoToVeloxQueryConfigTest.cpp presto-native-execution/presto_cpp/main/TaskResource.cpp presto-native-execution/presto_cpp/main/PrestoServerOperations.cpp presto-native-execution/presto_cpp/main/http/HttpServer.cpp presto-native-execution/presto_cpp/main/operators/BroadcastExchangeSource.cpp presto-native-execution/presto_cpp/main/operators/ShuffleExchangeSource.cpp presto-native-execution/presto_cpp/main/operators/ShuffleWrite.cpp
