feat: profile mame2000, migrate bios_zips to structured files

Replace bios_zips section with structured files entries (category:
bios_zip, contents: with name/description/size/crc32) across all 4
MAME profiles. Profile mame2000 from source (was false alias of
mame2003_plus). Adds neogeo.zip, decocass.zip, hiscore.dat, cheat.dat.

+  Frozen snapshot of MAME 0.37b5 via iMAME4All (David Valdeita). Fastest and
+  least accurate MAME core. Supports ~2000 arcade games from the 0.37b5 ROM set.
+
+  BIOS handling follows MAME 0.37b5 conventions. Shared BIOS files are packaged
+  as parent ROM ZIPs (e.g. neogeo.zip) and placed in the ROM directory alongside
+  game ROMs. The core searches only the ROM directory for ROMs and BIOS sets.
+
+  Samples (per-game WAV files) are loaded from system_dir/mame2000/samples/.
+  They provide sound effects for certain games and are optional.
+
+  hiscore.dat and cheat.dat are loaded from the ROM directory (not system_dir).
+  Both are bundled in the repo's metadata/ directory.
