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.

 notes: |
-  SimCoupe is an emulator for the SAM Coupe, a British 8-bit home
-  computer by Miles Gordon Technology (1989). The SAM Coupe was
-  designed as a successor to the ZX Spectrum with a Z80B CPU at 6 MHz
-  and custom ASIC graphics.
+  SAM Coupe emulator by Simon Owen. Port based on old pre-1.0 SimCoupe
+  codebase. Experimental, incomplete (no sound, partial input).
 
-  No external BIOS or ROM files required. The SAM Coupe ROM is built
-  into the emulator. The libretro wrapper does not request any files
-  from the system directory.
+  SAM Coupe ROM v3.0 and SAMDOS 2.0 embedded in the binary (SAMROM.h,
+  SAMDOS.h). HDBOOT patches for Atom Lite also embedded (HDBOOT.h).
+  The libretro wrapper never accesses the system directory.
 
-  Loads .dsk, .sad, .mgt, .sbt, and .cpm disk images as content.
+  Upstream v1.2.x loads external resource files (samcoupe.rom,
+  sp0256-al2.bin for VoiceBox speech synthesis). The libretro port
+  lacks VoiceBox/SP0256 support (commented out in IO.cpp).
