feat: profile armsx1 0.3.6 on swanstation

The Android build now runs libretro SwanStation instead of psxe. Its importer accepts only 512 KB images whose MD5 is in a 25-entry table (Ps1BiosProbe.java:29-55), so the agnostic scph1001.bin entry becomes those 25 identified images. psxe now refuses sizes other than 512 KB and 1 MB (psx/dev/bios.c:44-49).
