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: |
-  TempGBA is a Game Boy Advance emulator forked from gpSP. Originally
-  developed for the Nintendo DS homebrew scene, the libretro port wraps
-  the dynarec-based GBA engine for use in RetroArch.
-
-  The GBA BIOS (gba_bios.bin) is optional. TempGBA includes HLE BIOS
-  stubs inherited from gpSP that handle most SWI calls. The real BIOS
-  improves boot logo display and SWI accuracy for a small number of
-  titles.
-
-  BIOS file goes in the system directory as gba_bios.bin (same path
-  used by gpSP and mGBA).
+  Fork chain: gpSP (Exophase) -> gpSP Kai (takka) -> TempGBA NDS
+  (Nebuleon) -> TempGBA4PSP (unknown) -> TempGBA-libretro.
+  PSP-optimized GBA emulator. No HLE BIOS: SWI calls execute from
+  the real BIOS ROM. The NDS version (ReGBA) added an open-source
+  BIOS replacement (Normmatt), but TempGBA4PSP did not carry it over.
+  Boot sequence skipped by default (PC starts at 0x08000000).
