The clean target previously removed all artifacts with a single glob pattern. This change explicitly separates the removal of the build directory, release artifacts (wren, libwren.a, libwren.so), and debug artifacts (wrend, libwrend.a, libwrend.so) into distinct rm commands for clarity and maintainability.
