feat: re-profile 22 emulators, refactor validation to common.py

batch re-profiled nekop2 through pokemini. mupen64plus renamed to mupen64plus_next. new profiles: nes, mupen64plus_next. validation functions (_build_validation_index, check_file_validation) consolidated in common.py — single source of truth for verify.py and generate_pack.py. pipeline 100% consistent on all 6 platforms.

+  is part of the PicoDrive source tree (platform/libretro/).

  Mega CD / Sega CD games require a region-matching BIOS file. The core searches
  the system directory for each name in order, trying .bin then .zip extension,
  and uses the first file found. If no BIOS is found, CD games fail to load with
  PM_BAD_CD_NO_BIOS. MSU-MD games can run without BIOS.
