feat: re-profile 37 emulators with upstream verification

Browse Source 
source-verified core_classification, upstream URLs, validation fields,
and hle_fallback flags. trimmed verbose notes. removed phantom files
(azahar boot9/sector0x96). added bsnes2014 variant profiles.

b2 is a BBC Micro emulator by Tom Seddon. Libretro port by Zoltan Balogh.
Libretro port by Zoltan Balogh of Tom Seddon's b2 BBC Micro emulator.

Standalone: loads ROMs from etc/roms/ via GetAssetPath().
Standalone loads ROMs from etc/roms/ via GetAssetPath() + LoadFile().
ref: tom-seddon/b2/src/b2/roms.cpp:9-10
Libretro port (experimental): GetAssetPath stubbed in
src/libretro/adapters.cpp to return relative paths. LoadFile also
stubbed (returns false). ROM loading mechanism unclear — the 256 ROM
files are in the repo but the stub suggests they may not load at runtime.
is_experimental=true in .info.
ref: zoltanvb/b2-libretro/src/libretro/adapters.cpp
Libretro port embeds all ROMs as hex arrays in src/libretro/roms.hpp.
create_core() loads OS and sideways ROMs from static machine_types[] arrays.
GetAssetPath() and LoadFile() are stubbed — no file I/O at runtime.

256 ROM files in etc/roms/ cover: BBC Model B (OS 1.20, BASIC II),
Model B+ (B+MOS), Master 128 (MOS 3.20, 3.50), Master Compact
(MOS 5.00, 5.10, I5.10C/Olivetti), parasite processors (65C102 TUBE,
6502 TUBE), disc interfaces (Acorn 1770, Watford, Opus).
All ROMs ship with both standalone and libretro repos.
No external BIOS files needed by the user for either mode.
9 machine types: B/Acorn 1770, B/Watford DDB2, B/Watford DDB3,
B/Opus 1770, B/Opus Challenger 256K, B/Opus Challenger 512K,
B+, B+128, Master 128 (MOS 3.20).
Master 3.50, Master Turbo, Master Compact not yet implemented.

# 256 ROMs bundled in repo etc/roms/ — not loaded from system dir
# standalone loads via GetAssetPath("roms", path) -> etc/roms/
# libretro port has LoadFile stubbed — ROM loading mechanism TBD
# is_experimental=true, core may not fully function
# closed-source analysis note: core binary on buildbot contains
# "Retro ROM DIRECTORY" and "system_dir" strings but LoadFile stub
# returns false. needs further investigation when port matures.
# all ROMs embedded in binary via roms.hpp — no external files needed
# .info firmware_count=0 matches code reality
