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

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.

 notes: |
-  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
+  directory access. The core accepts .cas cassette content and can boot
+  directly into P2000T BASIC with no content loaded.

-      InitP2000() allocates 20K (0x5000) for ROM and 4K for VRAM.
-      The monitor ROM occupies the first 4K, the BASIC cartridge ROM
-      occupies the next 16K. In the libretro build, both are passed
-      as in-memory byte arrays from the embedded header.
