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

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
