feat: profile jumpnbump, kronos, lowresnx, lutro, m2000

Browse Source 
add core_classification and upstream to all five profiles. kronos:
add ROM cartridge files (mpr-18811-mx.ic1, mpr-19367-mx.ic1), add
archive: field to STV blobs, remove unverified MD5 hashes, fix
cores list (remove yabause_libretro). jumpnbump: fix incorrect
note about embedded data. lowresnx, lutro, m2000: add missing
classification fields.

Libretro port of Jump 'n Bump, a multiplayer bunny-stomping platformer

Game data (sprites, levels, sounds) is compiled into the binary.
No content file, BIOS, or system directory files required.
originally by Brainchild Design (1998). Released as freeware under GPL.
The core loads a .dat archive file as content via retro_load_game().
All game resources (sprites, sounds, levels, fonts, music) are packed
inside the .dat file. No system directory files, BIOS, or firmware
required. The .dat file is built from the data/ directory by the
jnbpack tool in the upstream repo.
Extra levels are available from brainchilddesign.com as additional
.dat files.

Kronos is a Sega Saturn and ST-V arcade emulator forked from Yabause.
The libretro repo at libretro/yabause ships the older "Yabause" core
(yabause_libretro) which handles Saturn only and has no STV support.
Kronos is a Sega Saturn and ST-V arcade emulator by FCare, forked from
Yabause. Requires OpenGL 4.3 compute shaders.

ST-V BIOS: {system}/kronos/stvbios.zip or {system}/stvbios.zip
MAME-style ZIP containing region-specific EPROMs. Kronos picks the best

ST-V BIOS (Kronos only):
{system}/kronos/stvbios.zip or {system}/stvbios.zip
The ZIP is a MAME-style romset containing region-specific EPROMs.
Kronos picks the first matching BIOS by region, with a configurable
"favorite region" core option (EU/US/JP/TW). The ZIP must contain
at least one of the BIOS blobs listed below. ST-V games are detected
automatically when loading a .zip file.
ROM cartridges for KOF95 and Ultraman are auto-detected via game database
(db.c) and loaded from system_dir when the corresponding game is running.

LowRes NX is a fantasy console simulating an imaginary 8/16-bit handheld.
It runs programs written in a custom BASIC dialect, loaded as .nx files.
The libretro port is maintained by the upstream author (timoinutilis) in
the same repository.
The libretro port reads game content entirely through the retro_game_info
data buffer (need_fullpath = false, libretro_main.c:317). The .nx source
code is copied into memory at retro_load_game() (libretro_main.c:490)
and compiled by the built-in interpreter.
The boot intro sequence is compiled from bootIntroSourceCode, a string
constant embedded in boot_intro.c -- not loaded from any external file.
The core never calls RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY. There is
no code path that reads any file from the system directory. No BIOS,
firmware, or boot ROM is required.
The virtual machine provides a 160x128 screen, 64 colors, 256 8x8
sprites, 4-channel sound, d-pad + 2 buttons, and a pause button.
retro_load_game() copies the .nx source code into memory
(libretro_main.c:490) and compiles it with the built-in interpreter.

M2000 is a Philips P2000T home computer emulator ported to libretro.
M2000 is a Philips P2000T home computer emulator by Dion Olsthoorn,
based on the original emulator by Marcel de Kogel (1997). The libretro
port is maintained by the same author in the same repository.
The libretro port does NOT require any external BIOS or ROM files.
All required ROMs are compiled directly into the core binary via
src/libretro/m2000_roms.h:
All ROMs are embedded in the binary via m2000_roms.h:
- monitor_rom (4096 bytes, 0x0000-0x0FFF)
- basic_nl_rom (16384 bytes, 0x1000-0x4FFF)
- SAA5050 teletext font (m2000_saa5050.h)
- monitor_rom (4096 bytes) - P2000T monitor ROM, loaded at 0x0000-0x0FFF
- basic_nl_rom (16384 bytes) - Dutch BASIC cartridge ROM, loaded at 0x1000-0x4FFF
The SAA5050 teletext font is also embedded via src/libretro/m2000_saa5050.h.
retro_init() at src/libretro/m2000_libretro.c:444 calls:
InitP2000(monitor_rom, basic_nl_rom)
which copies the embedded arrays directly into the ROM memory space
(src/P2000.c:282-283 and 308-311), bypassing all file I/O.
The standalone (non-libretro) version loads these as external files:
- P2000ROM.bin (monitor ROM, 4096 bytes)
- BASIC.bin (BASIC cartridge ROM, 16384 bytes)
- Default.fnt (SAA5050 font, 2240 bytes)
These files exist in the repo root for the standalone build only.
The core accepts .cas (cassette) content and can also run with no
content to boot directly into P2000T BASIC.
retro_init() calls InitP2000(monitor_rom, basic_nl_rom) which copies
the embedded arrays into ROM memory (P2000.c:282-311). No system
