Thirty platform system ids, such as sufami, pokemini, vsmile, and
Recalbox's comma-joined msx1,msx2, matched no system any profile
names, so no core file was attributed to them and --system missed them.
The scraper maps now carry those names, and a test holds every platform
system to a profile system apart from two named folds.
RetroBat's platform file carried no core list, and a registry list
copied from Batocera stood in with ports RetroBat never runs and none
of its standalone emulators marked as such. The scraper now reads
es_systems.cfg at the release tag: libretro cores, and every other
emulator as standalone.
resolve_platform_cores() links platforms to their cores via
three strategies: all_libretro, explicit list, system ID
fallback. Pack generation always includes core requirements
beyond platform baseline. Case-insensitive dedup prevents
conflicts on Windows/macOS. Data dir strip_components fixes
doubled paths for Dolphin and PPSSPP caches.
