refactor(task): use asKeyValueRange() for Qt container iteration

This improves iteration over the compilerConfiguration map by replacing toStdMap() with asKeyValueRange(). This Qt 6+ feature provides a lightweight view over the container's key-value pairs, eliminating the unnecessary intermediate std::map allocation.
