Convert the production source files in src/ (69 .c/.cpp) and test/jemalloc_test.h.in to list the headers they actually use, then delete the umbrella. Three consolidated headers (peak_event.h, prof_sys.h, sz.h) also gain explicit transitive includes. Every translation unit now declares what it uses. A missing include now fails at the failing file rather than silently working because something upstream pulled in the world.
