feat: re-profile 40 emulators, harden CI workflows

profile emulators pd777 through tic80, add frozen snapshots
(puae2021, snes9x2002/2005/2010, stella2014/2023).

CI: replace github-script with gh CLI, add test execution,
job-level permissions, propagate changed output, pin jsonschema.

-  SMS Plus GX is a Sega Master System / Game Gear emulator with additional
-  support for ColecoVision, SG-1000 and Sord M5 via TMS9918 VDP emulation.
+  Enhanced fork of Charles MacDonald's SMS Plus 1.3 by Eke-Eke (GX) and
+  gameblabla. Master System, Game Gear, ColecoVision and SG-1000 emulator.
+  Standalone ports also support Sord M5 (behind SORDM5_EMU compile flag,
+  not compiled in libretro build).
 
-  BIOS loading happens in bios_init() (smsplus_libretro.c:203-252).
-  Two BIOS files are supported:
+  BIOS loading in bios_init() (smsplus_libretro.c:203-252). bios.sms is
+  always attempted but only activated when core option smsplus_sms_bios is
+  "auto" (default: disabled). BIOS.col is loaded only for ColecoVision
+  ROMs and required for them. Standalone ports use BIOS.sms (uppercase)
+  instead of bios.sms.
 
-  1. bios.sms -- Sega Master System boot ROM. Optional. Loaded for all
-     console types. A core option "smsplus_sms_bios" (default: disabled)
-     controls whether it is used. When set to "auto" and the file exists,
-     bios.enabled is set and the SMS boot sequence plays before games.
-
-  2. BIOS.col -- ColecoVision BIOS. Required for ColecoVision ROMs only.
-     Loaded into coleco.rom (0x2000 bytes = 8 KB). Without it, ColecoVision
-     games will not start and the core logs an error. The filename is
-     case-sensitive (uppercase BIOS, lowercase .col).
-
-  Both files are read from the system directory root (no subdirectory).
-  Path is built as: system_dir + "/" + filename (smsplus_libretro.c:211,234).
-
-  Console type is auto-detected from ROM file extension:
-    .col -> CONSOLE_COLECO
-    .sg  -> CONSOLE_SG1000
-  Or forced via the "smsplus_hardware" core option.
+  .info marks BIOS.col as optional (firmware1_opt=true) but the libretro
+  code returns false from retro_load_game() when BIOS.col is missing for
+  .col ROMs.
