Subject: [PATCH] feat: add regional nand aliases to melonds profile

dsi_nand.bin aliases: DSi_Nand_USA/EUR/JPN/AUS/CHN/KOR.bin
for repo resolution. Code loads a single configurable path
(libretro.cpp:836, EmuInstance.cpp:1036-1050), validates
nocash footer (DSi_NAND.cpp:42-111). size + storage added.
