Abdessamad Derraz 11da070128 chore: recale the profile refs onto their pins
Upstream moved under 145 profiles: 679 refs shifted and 452 followed a
renamed file, against 6,483 that still anchor where they were written.
The recale rewrites the located ranges only, keeping the annotations and
the sentences that carry them, and 106 pins advance in the same commit
because refs and source_commit name one revision or the profile
describes two at once.

Nothing here was guessed. The 183 refs that are CHANGED, GONE or
AMBIGUOUS are untouched, and the 57 profiles holding them keep their old
pin until someone reads the diff: profile_sync refuses to recale a
profile while any of its refs needs a re-read. trident kept its pin too,
its annotated ref being one the writer will not rewrite.

notes: |
Kronos is a Sega Saturn and ST-V arcade emulator by FCare, forked from
Yabause. Requires OpenGL 4.3 compute shaders.
Saturn BIOS search order:
1. {system}/kronos/saturn_bios.bin
2. {system}/saturn_bios.bin
3. {system}/sega_101.bin
4. {system}/mpr-17933.bin
First file found wins. Real BIOS required (HLE deprecated, only available
via kronos_force_hle_bios core option for debugging).
ST-V BIOS: {system}/kronos/stvbios.zip or {system}/stvbios.zip
MAME-style ZIP containing region-specific EPROMs. Kronos picks the best
match by game region and kronos_stv_favorite_region core option (EU/US/JP/TW).
ROM cartridges for KOF95 and Ultraman are auto-detected via game database
(db.c) and loaded from system_dir when the corresponding game is running.
BIOS loading: libretro.c retro_load_game() lines 1601-1727.
STV blob table: ctrl/src/stv.c BiosList lines 112-136.
ROM cartridge DB: utils/src/db.c lines 43-45.
Standalone supports MPEG card ROM loading (Video CD card); disabled in
libretro port (mpegpath = NULL in yabause/src/libretro/libretro.c:1578).
