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: |
ColecoVision emulator by Ignacio Sanchez (drhelius). Official port
maintained by the upstream author. The ColecoVision BIOS ROM is required.
Without it, the core renders a static placeholder image (kNoBiosImage from
no_bios.h) and games do not execute.
The libretro wrapper (platforms/libretro/libretro.cpp:295-308) tries "colecovision.rom" first,
then falls back to "coleco.rom". Both resolve to the same LoadBios() call
in src/Memory.cpp:256-287 which validates size == 0x2000 (8192 bytes) only.
No hash check is performed.
On reset, BIOS byte at offset 0x69 is patched for region selection:
0x3C for NTSC, 0x32 for PAL (src/Memory.cpp:206-209).
SGM (Super Game Module) expanded RAM requires no additional BIOS files.
