feat: 4-source verified emulator profiles (A-E cores)

Browse Source 
33 emulator profiles created or updated with systematic
verification against libretro docs, .info, core source,
and original emulator source code.

New profiles: bsnes-jg, bsnes2014, bsnes_cplusplus98,
bsnes_hd_beta, bsnes_mercury, citra2018, citra_canary.

Key fixes:
- dosbox_svn/svn_ce: not aliases of dosbox_core (no MUNT)
- beetle_psx: alt_names renamed to aliases (field bug)
- dolphin: added 15 Realtek BT firmware for Wiimote passthrough
- dosbox_core: added CM-32LN, 13 split ROM pairs for standalone
- duckstation: type standalone+libretro, 106 BIOS verified
- snes9x/np2kai: formal aliases for alternate filenames

verification: md5
notes: >
DuckStation auto-detects BIOS by MD5 hash. It accepts PS1, PS2 and PS3 BIOS images
(only the first 512 KB are mapped). Each image has a priority score - lower is better.
Images with region_check=true enforce region matching for disc booting.
PS2 BIOS images are deprioritized (priority >= 100) due to requiring dynamic fast boot patches.
Late PAL revisions are further deprioritized due to additional regional checks.
OpenBIOS is detected by signature at offset 0x78, not by hash.

DuckStation auto-detects BIOS by MD5 hash from a flat scan of the BIOS directory.

Accepts PS1 (512 KB), PS2 (4 MB), and PS3 (0x3E66F0) BIOS images.
ref: src/core/bios.h:24-26 (BIOS_SIZE, BIOS_SIZE_PS2, BIOS_SIZE_PS3)
Only the first 512 KB are mapped (bios.cpp:212).
105 known BIOS entries (24 PS1 + 80 PS2 + 1 KDL-22PX300) identified by MD5.
ref: src/core/bios.cpp:34-139 (s_image_info_by_hash)
Each image has: region, region_check, fast_boot_patch type, priority score.
Lower priority = preferred. PS2 deprioritized (>= 100) for dynamic fast boot.
Late PAL deprioritized (>= 150) due to additional regional checks.
OpenBIOS detected by signature at offset 0x78, not by hash.

Standalone: BIOS dir = EmuFolders::Bios (configurable, default bios/).

Libretro: BIOS dir = RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY (flat).
The libretro core was removed by the author (license change to non-commercial).
The .info file and buildbot builds still exist from community forks.
