Renames savefile_t to saveslot_t and folds last session's standalone settings.h/.c module back in as savemeta_t, so there's one save system (SAVE.slots[] + SAVE.meta) instead of two parallel ones - while letting each platform pick its own physical format for the two concepts: - Linux now writes human-editable JSON (slot0.json, settings.json, ...) via yyjson's mutable writer API, so players can hand-fix a bad setting. - PSP folds meta into the same sceUtilitySavedata binary payload as its one save slot (SAVE_SLOT_COUNT_MAX=1 there - a future save picker will let players manage multiple named saves via the OS's own browser). - GameCube consolidates the 3 per-slot memory card files and the separate settings file into one combined card file. Also fixes two bugs surfaced while building this: the CRC finalize step seeked to a hardcoded offset (only safe for one section per file, breaks once meta+slots share a buffer), and save.c's async/sync dispatch left an unconditional fallback call that doesn't exist on PSP-only platforms.
