feat: re-profile 37 emulators with upstream verification

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.

 notes: |
-  bsnes-mercury is bsnes v094 with Mercury optimizations: HLE for DSP
-  and Hitachi coprocessors, firmware_appended support, overclocking.
+  Fork of higan v094 by Alcaro. Restores HLE for coprocessor chips removed
+  in v094, adds firmware_appended support and SuperFX overclocking.
   Three profiles: accuracy, balanced, performance (PPU differs, not firmware).
-  .info says performance has 17 fw (no cx4) but the code compiles CX4 LLE
-  in all profiles — cx4.data.rom works in performance too. The .info is wrong.
-  Core option bsnes_chip_hle (default LLE) controls HLE/LLE at runtime.
-  ref: target-libretro/libretro.cpp altImplementation(), "bsnes_chip_hle"
+  Core option bsnes_chip_hle (default LLE, requires bsnes_violate_accuracy)
+  controls HLE/LLE at runtime. ref: target-libretro/libretro.cpp:428-442
 
-  Same firmware loading as bsnes2014: system_dir via file::exists +
-  mmapstream. No BS-X auto-load from system_dir (subsystem only).
-  ref: target-libretro/libretro.cpp:245-254

-  HLE fallback for DSP1/1B/2/4, Hitachi/CX4, ST010.
-  ref: sfc/cartridge/markup.cpp:351,404,618
+  Firmware loaded from system_dir via file::exists + mmapstream.

   firmware_appended: firmware can be appended to end of ROM file.

-  SGB boot ROM NOT embedded (sgb.boot.rom from system_dir).
-  CX4 NOT embedded (cx4.data.rom from system_dir).
+  SPC700 IPL ROM (64 bytes) is embedded in the binary.
+  ref: target-libretro/libretro.cpp:39

+  Upstream higan v094 by byuu (2014, site defunct). Mercury preserves v094
