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

 notes: |
-  Citra (now Azahar, formerly Lime3DS) uses HLE for most system services,
-  so many files are optional. AES keys are the most important for decrypting
-  games and system data. Shared font has a built-in fallback.
-  File locations relative to user dir: sysdata/ for keys/boot/font/otp/seeddb,
+  Citra 3DS emulator (pre-Azahar). Data dir: citra-emu.
+  HLE for most services — files optional. AES keys most important.
+  File locations: sysdata/ for keys/boot/font/seeddb,
   nand/ for NAND filesystem, nand/private/ for movable.sed.
-  Legacy data dirs: citra-emu, lime3ds-emu -> azahar-emu.
+  ref: src/common/common_paths.h:67-70
+
+  Key file: aes_keys.txt (NOT keys.txt — that's Azahar).
+  ref: src/common/common_paths.h:68
+
+  Azahar fork: see emulators/azahar.yml (uses keys.txt, data dir azahar-emu).
+  citra_canary: same repo, see emulators/citra_canary.yml.
