Test that a process using HTTP server lifecycle (start/stop) exits cleanly without crashing. On Windows with PThreads4W, the library's DllMain(DLL_PROCESS_DETACH) runs after PL_cleanup() has freed thread data. Without explicit cleanup via pthread_win32_process_detach_np(), this causes ACCESS_VIOLATION in Debug builds where the CRT fills freed heap with 0xDD. The test spawns a subprocess that starts and stops an HTTP server, then halts. The HTTP server creates worker threads and allocates enough memory that PL_cleanup() triggers the crash in Debug builds. The parent verifies the exit code is 0 (not a crash). @see pthread_win32_process_detach_np() in src/pl-init.c

Uses HTTP server start/stop pattern to reliably reproduce threading cleanup issues. Details in commit message.
