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.

-  Numero is a TI-83 family calculator emulator for libretro, based on the
-  Wabbitemu emulator. Supports TI-83, TI-83 Plus and TI-83 Silver Edition.
+  Libretro port of Wabbitemu, a TI-83 family calculator emulator.
+  Supports TI-83, TI-83 Plus and TI-83 Plus Silver Edition.
 
-  A calculator ROM dump is required to run. The core searches for ROM files
-  in the system directory root with a fixed priority order
-  (libretronew.cpp:575-594):
+  A calculator ROM dump is required. The core searches sequentially in the
+  system directory (libretronew.cpp:575-594): ti83se.rom first, then
+  ti83plus.rom, then ti83.rom. The first found is loaded via rom_load()
+  (libretronew.cpp:608). file_present_in_system() checks existence only
+  via VFS open/close (libretronew.cpp:451-472). No hash or size validation.
 
-  1. ti83se.rom   (TI-83 Silver Edition, recommended -- largest storage)
-  2. ti83plus.rom (TI-83 Plus)
-  3. ti83.rom     (TI-83)
+  Without any ROM, the core shows a blank screen listing the expected
+  filenames (libretronew.cpp:1030-1042). No HLE fallback.
 
-  The first file found wins. file_present_in_system() checks existence only
-  (libretronew.cpp:451-472), then rom_load() loads it (libretronew.cpp:608).
+  Supports no-content launch (libretronew.cpp:556). Content files
+  (.8xp/.8xk/.8xg) are loaded on top of the running ROM via link cable
+  simulation. Auto-saves calculator state every 10 seconds
+  (libretronew.cpp:1050-1063).
 
-  There is no fallback or built-in ROM. If none of the three files are found,
-  the core starts without a BIOS and shows a blank screen with a status
-  message listing the expected filenames (libretronew.cpp:1034-1041).
-
-  The core supports no-content launch (RETRO_ENVIRONMENT_SET_SUPPORT_NO_GAME
-  is set to true, libretronew.cpp:555-556). Content files are .8xp/.8xk/.8xg
-  calculator programs loaded on top of the running ROM.
-
-  The emulator auto-saves calculator state every 10 seconds to preserve RAM
-  contents (the TI-83 has no persistent storage beyond battery-backed RAM).
+  Upstream Wabbitemu supports a wider model range (TI-73 through TI-84+CSE)
+  but the libretro wrapper only searches for TI-83 family filenames. The
+  underlying engine (calc.cpp:rom_load) auto-detects the model from the ROM
+  header.
