Abdessamad Derraz ebb55a445b 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: |
Fork of the last GPLv3 release of redream (inolen) before it went closed-source.
The core has HLE bootstrap -- when boot.bin is missing, bios_invalid_instr()
traps at PC=0x0 and calls bios_boot(), which loads IP.BIN and 1ST_READ.BIN
directly from disc, sets up syscall vectors, and starts execution at 0xac008300.
The fork sets appdir to the RetroArch system directory root
(retro_host.c:216-217), unlike the upstream which appends /dc
(upstream retro_host.c:196-198). The .info still declares dc/ prefix paths
matching the upstream, not this fork.
boot.bin is validated against four known MD5 hashes (boot.c:25-30).
Validation failure logs a warning but the core continues via HLE.
flash.bin is read/write. If missing, bios_validate_flash() resets all
partitions to defaults. Saved back to disk on shutdown (flash.c:197-199).
