Introduce conditional detection of Darwin target to set appropriate shared library flags and extension (.dylib instead of .so). Refactor static and shared library build targets into combined `libwren` and `libwrend` phony targets that produce both .a and .dylib/.so files, and update .gitignore to exclude the new .dylib artifacts.
