feat: re-profile 12 emulators, fix dosbox_core regression

batch re-profiled clownmdemu through dosbox_core with upstream
verification. restored dosbox_core mt-32/cm-32l rom halves removed
by batch (14 files), added core_classification. regenerate database.

No BIOS or firmware files required. The .info file declares firmware_count = 0.
Games fall into two categories:
- ROM-based: shipped as MAME-style ZIP archives (filename matters).
The core loads the ZIP passed by the frontend and matches individual ROM
chips by CRC32 (chips/rom.cpp:41-218, RomDesc::get_data). If a chip's
CRC does not match, the core walks all entries in the archive looking for
a CRC match or alt_crc match.
- ROM-less: games like Pong, Breakout, Rebound whose original PCBs had no
ROM at all. These use .dmy dummy launcher files (empty placeholders) to
tell RetroArch which game to start.
retro_get_system_info (libretro.cpp:122-137) sets need_fullpath = true,
block_extract = true, valid_extensions = "zip|dmy|k1|a1|6c|c6|d2|s1|f4|a4|
1da|da1|C4|4c|4d|d7|d4". The unusual extensions are raw ROM chip dumps for
individual games (e.g. .k1 for antiaircraft, .a1 for attack).
dice.cpp:42-66 strips any "#inner.rom" suffix from the path (for ROM
managers that expose zip contents) and passes the zip path to
RomDesc::set_zip_filename.
retro_init (libretro.cpp:50-63) retrieves RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY
but uses it only for the retro_base_directory variable, not for loading any
system files.
Games with ROMs (10 titles):
antiaircraft.zip - 1 ROM chip (k1)
attack.zip - 6 ROM chips (a1, b1, c1, d1, j6, k6), each with alt_crc
cleansweep.zip - 3 ROM chips (6c, d7, k3)
crashnscore.zip - 6 ROM chips (d2, e2, f6, f7, p6, p7)
indy4.zip - 4 ROM chips (s1, s2, c1, c2)
jetfighter.zip - 6 ROM chips (a4, j1, j5, k5, m1, r5)
sharkjaws.zip - 2 ROM chips (1da/da1, 1db/db1)
steeplechase.zip - 2 ROM chips (C4, D4); bugle ROM c8 dump missing
stuntcycle.zip - 2 ROM chips (4d, 1fh)
wipeout.zip - 2 ROM chips (d4, g7)
ROM-less games (11 titles, use .dmy dummy files):
breakout, crossfire, gotcha, hiway, pinpong, pong, pongdoubles,
quadrapong, rebound, spacerace, tvbasketball
Games load as MAME-style ZIP archives matched by CRC32 per ROM chip
(chips/rom.cpp:41-218). ROM-less games (Pong, Breakout, etc.) use .dmy
dummy launcher files. The system directory is retrieved but never used
for file loading (libretro.cpp:60-62).
