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.

+notes:
+  rom_structure: >
+    All ROM files are loaded relative to the RetroArch system directory via
+    romfopen(). Machine BIOS ROMs go in roms/<machine_name>/ subdirectories.
+    Video card ROMs go directly in roms/ (or roms/<card>/ for some).
+    Which ROMs are needed depends on the selected machine model and video card.
+  minimum_requirement: >
+    At minimum, mda.rom (font) and one machine BIOS set are required.
+    The video card ROM for the selected GPU is also needed unless the machine
+    has built-in video (PCjr, Tandy, Amstrad, Acer 386SX, PS/1).
+  libretro_version: >
+    The libretro port is PCem-mooch v11, a community fork based on PCem v10.1.
+    Upstream PCem has evolved to v17 with many more machines and devices.
+  nvr_files: >
+    NVR files are CMOS/NVRAM templates providing pre-configured BIOS settings.
+    Shipped with the PCem distribution. Without them the BIOS starts with blank
+    CMOS (user must manually configure). The emulator also writes these back on
+    shutdown.
+  runtime_state: >
+    The emulator creates additional state files during operation: ATI EEPROM
+    (ati18800.nvr, ati28800.nvr, mach64.nvr), Intel flash (dmi.bin, escd.bin
+    per Pentium machine). These are emulator-generated and not included here.
+  info_divergence: >
+    The .info declares zero firmware (no firmware_count field). The core
+    actually loads 89+ ROM files plus NVR/EEPROM templates.
