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: |
FCEUmm (FCE Ultra mappers modified) is a NES/Famicom emulator forked from
FCEU Ultra by CaH4e3. FDS games require the FDS BIOS ROM (disksys.rom).
Game Genie emulation requires gamegenie.nes when the core option is enabled.
An external palette file (nes.pal) overrides the built-in palette when the
core option is set to Custom.
File path construction: src/general.c FCEU_MakeFName() joins the system
directory with each filename directly - no subdirectories.
