Two upstream improvements integrated: 1. wchar.h cbindgen.toml — adopt upstream include ordering: - Remove redundant wchar_t redefinition (now provided by bits/wchar-t.h) - Define wint_t BEFORE #include <stddef.h> (conflict with GCC __need_wint_t) - Drop sys_includes, use no_includes=true (all includes in after_includes) - Cleaner circular-dependency breaking (wchar.h → stdio.h → inttypes.h → wchar.h) 2. stdbool.h — fix to POSIX standard: - Change 'typedef _Bool bool' to '#define bool _Bool' (C mode) - Remove 'typedef bool _Bool' (C++ mode, not in POSIX) - Only emit bool/true/false defines in C++ when __cplusplus < 201103L
